Operant Conditioning

Form of learning in which a voluntary response is strengthened or weakened, depending on the consequences which follow the behavior

Infants

Affected their environment

Affected by the effects their actions bring

Habituation Method

Conditioning Method

Electrode Recording Method (Foley, 2006)

Papousek (1959)

Infant

Cheek touch  Rooting reflex 25%

Cheek touch  Rooting  Ingestion of milk

Frequency of rooting reflex increased

Siqueland & Lipsitt (1966)

Newborns

Auditory Sd & stroke  Head turn  Sugar water

Other auditory stimuli & stroke  No head turn

Siqueland & DeLucia (1969)

4 months old

Conjugate reinforcement

High amplitude sucking (HAS)  Bright visual stimulus

Novel stimulus  HAS

Moon & Fifer (1990)

2 days old

Sd auditory string  Sucking  Mom’s voice

Sdelta auditory string  Sucking  Silence

Rheingold et al. (1959)

3 months old

Spontaneous vocalizations  Social stimuli

Increased vocalizations

Meltzoff & Kuhl (1989)

4 months old +

Change auditory stimulus  Head turn  Puppets

Rovee-Collier and colleagues

Infants

Conjugate reinforcement

Infant kicks  Mobile moves

3 min baseline/retention  9 min acquisition

 3 min immediate retention test/extinction

Sessions conducted 1 day+ apart

Infants

Visual stimulus

Infant gaze

Continued visual stimulus

Interesting

Bornstein and Sigmand (1986) & Slater

(1997) indicated infants who

Habituate more rapidly

Have short looking time

Greater preference for novelty

Higher IQ’s later

Could difficulties involving habituation represent a sign of or even predict a developmental delay?

Maybe…But I was not able to find any research specifically on this.

Toddlers with elevated autism symptoms showed slowed habituation to faces (Webb et al., 2010)

Some infant behaviors

Sucking

Vocalizations

Head & limb movements

Visual fixations

Important implications

Generality of operant reinforcement principles

Infant behaviors could be reinforced by changes behavior brings in environment

A type of automatic reinforcer in which the stimulus changes produced by the behavior increase the frequency of that behavior under similar circumstances. (Vaughan & Michael, 1982)

These reinforcers have a short life. Unlike

Primary reinforcers

Secondary reinforcers

Modification of stimulus or novel stimulus brings back rate of responding

Most potent means to study behaviors of developing children

Experiments demonstrate generality of the principles and efficacy of techniques of operant learning…so why the “cognitive revolution”?

Behavior analysts stuck on discrepancies between human and animals

Principle characteristic of ecological reinforcers

Convenient qualities

Seen as indicators

Operant procedure

Easy to implement

Variety of questions on early cognitive processes answered

Operant research in human learning follow operant chamber model

Relevant factors may not be effectively isolated

Baron et al. (1991)

Experimental variable are imposed long

Too Short

For many laboratories, learning contexts analyze in terms of exploration and problemsolving

Response rates not the most appropriate way to assess if learning has taken place

Operant chamber model to study infant learning is not adequate with ecological reinforcers

Not relevant within context of problem-solving analysis of operant behavior

Rate measure of operant behaviors do not appear most appropriate way to asses learning

Pomerleau et al. (1992)

Single-subject designs

“Non-perfect” contingency

Measures

Duration

% of opportunities

Latency measures

More relevant stimuli

Voltair, Gewirtz,& Pelaez (2005)

Synchronous reinforcement- reinforcing stimulus provided as long as individual engages in the behavior

Conjugate reinforcement - some property of a reinforcing stimulus varies proportional to a specific response attribute (e.g., rate, amplitude)

Stimulus elicits head turn and gaze orientation

Habituation

Repeated presentations

Allow infant to allocate behavioral resources to stimuli of greater relevance

Signal

Followed by appearance of attractive stimulus

Stimulus has a functional value

Behavior will ceases when

Stimulus loses its reinforcing value

Another behavior becomes more probable

This idea was met with resistance

Informational processing model: Contains more information to be processed

Functional model: More reinforcing

Sort out the effect of 2 functional values of stimuli on orienting response elicitation

Forty eight 4-month-olds

Three conditions

1.

2.

3.

12 presentations 2s visual stimulus

12 presentations 2s visual stimulus accompanied by another event

Visual stimulus on synchronous schedule

Visual stimuli

4x4 checkerboard pattern

8x8 checkerboard pattern

1 st pattern  2 nd 2 test trials  1 st 2 dishabituation trials

Suggest the importance of taking into account the functional value of stimuli when analyzing infant attention

Stimulus complexity is indeed a factor but will most likely be overshadowed by a stimulus with a signaling function

Looked at the respondent dimension of orienting response

Separate respondent and operant process

Respondent- Stimulus elicits head turn

Operant- Head turn makes stimulus appear

4 groups of 16

4 month-olds

Condition Description

Condition 1

1 stimulus a) elicits head turn, b) signals reinforcement, 3) synchronously reinforces visual exploration

Condition 2 1 stimulus constantly present

Condition 3

Condition 4

Stimulus appears if head turns toward illuminated surface. No eliciting stimulus.

SD different from the reinforcing stimulus

(signaled operant)

Stimulus appears if head turns to nonsignaled point in space. No eliciting stimulus. No SD.

Condition

Condition 1

(elic, sig,

SR+)

Condition 2

(const pres)

Condition 3

(no elic, SD)

Condition 4

(no elic, no

SD)

Results

Stimulus looked at less than Condition 3 &

4 but more than Condition 2

Stimulus looked at the least

Stimulus looked at the longest

Stimulus looked at the longest

Operant process, whether signaled or not, seems to be more potent in sustaining infant attention than

Stimulus that is always present

A stimulus whose sudden appearance triggers attention

Amodal- information that is not specific to an individual sensory system

Kraebel, 2009; Kraebel, 2012a & 2012b

Kraebel et al., 2004 (computer measures)

Infants given matching redundant amodal properties (e.g., viewed cylinders while holding a cylinder)  facilitated operant learning

Infants given mismatching redundant amodal properties (e.g., viewed cylinders while holding a rectangular cube)  inhibited operant learning

Why?

Are there any

Ample room for more research

Thanks!
