Effects of Choice Framing and Affect on Delay of Gratification

Abstract
Previous research on delay of gratification indicates that people have a
tendency to choose small rewards that are available immediately over more
valuable rewards that are available after a certain amount of time. This ability
to wait for the more valuable reward has been associated with a variety of
positive outcomes, such as better self-regulation abilities, academic success,
and reduced risk of addiction. One theory evoked to explain the inability to
delay gratification states that an emotional, impulsive “hot” system overrides a
rational, cognitive “cool” system and influences the person to act impulsively
and choose the small immediate reward. Various factors affecting how the
desired reward is presented can differentially activate the cool system to a
greater extent that the hot system. The role of affect in this decision-making
process is unclear as a result of contradicting evidence. The present study,
using a between-subjects design, used a modification of the Velten mood
statements to induce positive and negative affect, and attempted to activate the
cool system to a greater extent than the hot system by presenting the choice in
an impersonal manner. There were no significant differences between the
different conditions. Methodological flaws of the study are discussed.
Delay of gratification refers to the ability to wait a specified period of time for a large
reward instead of receiving a smaller reward immediately (Metcalfe & Mischel, 1999). Delay
discounting refers to the phenomenon in which the value of the larger reward decreases as the
delay for obtaining that reward increases (Metcalfe & Mischel, 1999). Delay of gratification was
first studied extensively in children (Metcalfe & Mischel, 1999); in a typical paradigm, a child is
presented with a reward such as candy or a toy, and informed that she can have two of the
desired items if she waits a specified amount of time (e.g. 15 minutes), or can choose to stop
waiting and receive the one item in front of her at any time (Metcalfe & Mischel, 1999).
Typically, the child will choose to wait, as two rewards are preferable to one, but over the
waiting period the temptation to receive a reward immediately often becomes overwhelming and

many children eventually choose to take the single item immediately (Metcalfe & Mischel,
1999). In adults, the task is often modified to involve choices between hypothetical amounts of
money (Green, Myerson, Lichten, Rosen, & Fry, 1996). The ability to delay gratification in this
type of paradigm is thought to be reflective of broader competencies (Metcalfe & Mischel,
1999), such as intelligence, resistance to temptation, and social responsibility (Mischel, Shoda, &
Rodriguez, 1989). Delay of gratification in adults has been correlated with college GPA’s
(Kirby, Winston, & Santiesteban, 2005) and SAT scores (Mischel et al., 1989), and negatively
correlated with addictive behaviours (Bickel & Marsch, 2001; Kirby, Petry, & Bickel, 1999).
The evidence that laboratory tests of delay of gratification have high relevance in real-world
measures of self-regulation (Metcalfe & Mischel, 1999) highlights the importance of gaining
knowledge of the factors that affect people’s ability to wait for a more valuable outcome.
Metcalfe and Mischel (1999) propose that this choice elicits competition between a “hot”,
emotional, impulsive system and a “cool”, cognitive system. In delay of gratification tasks, the
hot system influences the individual to act impulsively and select the immediate, less desirable
reward, while the cool system influences her or him to act rationally and wait for the more
desirable reward (Metcalfe & Mischel, 1999). Each system can dominate the other one,
depending on various individual and situational factors (Metcalfe & Mischel, 1999). For
example, how the stimulus of choice is presented can influence whether the hot or cool system is
predominantly activated (Metcalfe & Mischel, 1999). In a cool presentation of the stimulus, the
stimulus is presented in such a way that cool information about the object – for example, its
colour, shape and name – is available, but the hot information – for example, the feelings elicited
by eating it, if it is a food reward – is not as readily available (Metcalfe & Mischel, 1999). For
example, presenting a picture of the stimulus (cool presentation) in the place of the actual
CHOICE FRAMING AND AFFECT IN DELAY OF GRATIFICATION
183
stimulus (hot presentation); in such tasks, delay time is increased (Metcalfe & Mischel, 1999).
Delay time is also increased when the reward is out of sight during the wait period (Mischel &
Ebbesen, 1970), another situation in which the hot information is less accessibly (Metcalfe &
Mischel, 1999). Activation of the hot system can also be inhibited when attention is focused
elsewhere during the delay period (Metcalfe & Mischel, 1999). For example, children who were
given a toy to play with during the delay were much more likely to wait for the larger reward
than those without a toy (Mischel, Ebbesen, & Zeiss, 1972). Children who distracted themselves
by decreasing attention to the reward and increasing attention elsewhere in the room were more
successful at waiting than those who did not deploy attention elsewhere (Rodriguez, Mischel &
Shoda, 1989). All of these are thought to be situations in which ability to delay gratification is
enhanced due to greater activation of the cool system than the hot system (Metcalfe & Mischel,
1999).
Although various individual and situational factors affecting the tendency to delay
gratification have been studied (Metcalfe & Mischel, 1999), there is a paucity of research on the
role of affect. One study found that induced positive mood increased delay discounting in
extroverts (Hirsh, Guindon, Morisano, & Peterson, 2010). The authors hypothesized that this
was due to a preferential activation of the hot, emotional system in extroverts than in introverts
(Hirsh et al., 2010). However, another study with children found that those in whom a positive
mood was induced showed decreased discounting in comparison to negative-mood participants
(Moore, Clyburn & Underwood, 1976). In this case, the effect was explained by the hypothesis
that people in a positive mood are more likely to act rationally, while those in a negative affect
will seek anything that will immediately alleviate the negative state (Moore et al., 1976). The

effects of mood on delay discounting are unclear and the present study will attempt to elucidate
this ambiguity.
The purpose of the present study is to examine another possible mechanism of activating
the cool system over the hot system, and to further elucidate the effects of mood states on delay
of gratification. It was hypothesized that framing the delay task in a non-personalized manner
(i.e. as a choice another individual must make rather than a choice the participant must make)
will result in higher delay of gratification because this would result in preferential activation of
the cool system and therefore increased ability to delay, as the non-personal presentation would
elicit cool information about the stimulus without the corresponding hot information. Appetitive,
hot information was hypothesized to be less available due to the removal of a personal
perspective on the stimulus (rather than imagining themselves receiving the reward, the
participants will be imagining a different person receiving it). In addition, the effects of positive
and negative moods on delay of gratification will be examined. It was hypothesized that mood
will have more of an effect on the participants who received the delay choice framed as a
personal choice, because their hot, emotional systems will already be activated and therefore
they will be more responsive to emotional cues. Furthermore, in keeping with Moore et al.’s
(1976) theory, the positive mood was expected to produce greater delay of gratification than the
negative mood due to greater ability to act rationally rather than emotionally and impulsively
when in a positive mood.

Method
Participants
Twenty-six participants took part in the study. Nine of these were students at Huron
University College and participated in exchange for partial course credit in an introductory
psychology course. The remaining were recruited via word-of-mouth.
Materials
A sub-set of the Velten mood induction statements, obtained from Seibert and Ellis
(1991), were used to induce positive and negative moods. There were twenty-five statements
each in the positive and negative conditions, and each statement was presented individually for
six seconds via PowerPoint. The order of the statements was randomized for each participant,
and a slide containing instructions to read the statements and try to feel the mood conveyed by
them appeared at the beginning of the PowerPoint for every participant.
The delay of gratification task was a modified version of that used by Green et al. (1996),
in which participants were presented with a series of hypothetical choices between receiving
certain amount of money immediately, or $1000 in one year (see Appendix A). The choices of
the immediate reward ranged from $100 to $1000 and were always presented sequentially,
although they randomly alternated between ascending and descending between participants. In
the personal choice condition, the instructions before the first choice read as follows: “Imagine
you are going to make some choices between different amounts of money. For each choice,
please select the alternative you would choose in a real life situation. Which would you
choose?”. In the impersonal choice condition, the instructions read as follows: “Imagine a friend
of yours is going to make some choices between different amounts of money. For each choice,

186
please select the alternative you would advise your friend to choose. Which would you advise a
friend to choose?”
Procedure
After giving informed consent, participants were seated at a computer, presented with the
mood-induction PowerPoint, and instructed by the experimenter to follow the instructions
presented on the screen and inform the experimenter when the PowerPoint was finished. After
participants had sat through the PowerPoint, the experimenter presented them with the delay of
gratification task, again instructing them to follow the instructions on the screen. The entire
procedure took approximately 15 minutes.
Results
A 2 x 2 ANOVA was conducted with mood (with two levels: positive and negative) and
choice framing (with two levels: personal and impersonal) as the independent variables and
amount at which the switch from the delayed to the immediate reward was preferred as the
dependent variable. There was no main effect of mood, F(1, 21) = 2.07, p > 0.05, no main effect
of choice, F(1, 21) = 0.81, p > 0.05, and no mood by choice interaction, F(1, 21) = 0.71, p >
0.05. The results are displayed in Figure 1.
Discussion
Delay of gratification paradigms test an individual’s preference for a small reward
delivered immediately over a large reward received after a specified period of time (Metcalfe &
Mischel, 1999). Research indicates that the value of a large reward tends to decrease when
people must wait a certain period of time before receiving it, up to the point that many people
will choose a smaller reward immediately rather than wait for the larger reward (Metcalfe &
Mishcel, 1999). One theory that attempts to explain this illogical preference refers to the

dichotomy between a hot, emotional system that bases decisions after emotions and impulses and
a cool system that influences decisions to be rational (Metcalfe & Mischel, 1999). The tendency
to act irrationally and choose the small, immediate reward can be mitigated when the cool system
is activated over the hot system by presenting factual information which the cool system
responds to instead of appetitive information which the hot system responds to (Metcalfe &
Mischel, 1999). Another possible modulator of ability to delay gratification is affect, although
the effects of positive versus negative affect are less clear. Based on a previous study with
children in which positive mood lead to greater ability to delay gratification, it has been
theorized that a positive mood encourages rational thinking while a negative mood encourages
impulsive actions, influenced by the desire to select the option that will immediately relieve
negative affect (Moore et al., 1976). The present study sought to examine another possible
method of increasing ability to delay gratification by activating the cool system over the hot
system by presenting the choice as an impersonal rather than a personal choice, and sought to
replicate the previous finding of the effects of mood (Moore et al., 1976).
Unexpectedly, there were no differences between any of the conditions and no interaction
effect. It is quite possible that this lack of effect was due to the low number of participants in
each condition and then a stronger effect would be seen in a study using more people. It is also
possible that, although the premises for both conditions were correct, the actual manipulations
themselves were not strong enough to elicit an effect. For example, although the modified
Velten mood statements used in the present study have previously been found to reliably induce
the desired mood (Jennings, McGinnis, Lovejoy, & Sterling, 2000; Seibert & Ellis, 1991), the
Velten statements are not as reliable at eliciting a particular affective state as other mood
induction techniques (Westermann, Spies, Stahl, & Hesse, 1996). Furthermore, the Velten

statements have been shown to be more reliable at eliciting a negative mood than a positive one
(Westermann et al., 1996), so it is possible that the comparison was actually between a negative
mood and a neutral mood rather than a negative mood and a positive mood. This would not
totally explain the lack of effect, of course, for if there really was an effect of mood a negative
mood would be expected to differ from a neutral one. However, the difference between a
negative and neutral mood would be smaller than that between a negative and positive mood
which could have contributed to the lack of effect in conjunction with the other attenuating
factors. The personal choice manipulation may also not have been strong enough to elicit the
expected effect, perhaps because the choices in both conditions were hypothetical and thus were
less likely to activate the hot, impulsive system. Delay of gratification tasks are somewhat more
difficult to examine in adults because of the differences in what adults find rewarding versus
what children find rewarding (Green et al., 1976), but the effect may be present in a task that
involves real rather than hypothetical choices.
The ability to delay gratification in order to receive a more valuable reward after a
specified period of time rather than a less valuable one immediately is related to a variety of
positive outcomes such as self-regulation abilities (Mischel et al., 1989), academic success
(Kirby et al., 2005; Mischel et al., 1989) and reduced risk of developing addictions (Bickel &
Marsch, 2001; Kirby et al., 1999). Therefore the study of what factors contribute to this ability is
important as it can facilitate an increase in this ability in individuals who do not have it. The
present study did not find that framing a choice as an impersonal one or putting participants in a
positive mood improved this ability, but future studies with improved methodology may yet find
such results.
