Audit responses: responses maintained by access to existing self or coactor scores during non-social, parallel work, and cooperation procedures

Human subjects, mostly between 11 and 16 yr old, matched to sample for points that were exchangeable for money. An audit response was defined as a response maintained by allowing a subject access to an existing score on his own (self audit) or a coactor's (coactor audit) performance. In Experiment I, changes from non-social procedures (no coactor) to social procedures (coactor present) increased self and coactor audits. Since both types of audits occurred at about the same rates during cooperation and parallel work procedures, the increases did not depend on the subjects' response interactions. Although Experiment I did not demonstrate that subjects were comparing scores, the frequent occurrence of each kind of audit within a brief time period (interpersonal audit) did indicate that it was reinforcing to have both scores at the same time. These interpersonal audits suggested that the coactor's score increased self audits during social procedures. Experiment II supported this notion: relative to a non-social procedure, self audits increased more during a parallel work procedure when the coactor's score was accessible than when it was not accessible. Thus, increases in other behaviors that occur in the presence of a coactor, i.e., social facilitation, may also result from or be increased by providing a coactor's score.     

Interplay between action and movement intentions during social interaction

Observing the movements of another person influences the observer's intention to execute similar movements. However, little is known about how action intentions formed prior to movement planning influence this effect. In the experiment reported here, we manipulated the congruency of movement intentions and action intentions in a pair of jointly acting individuals (i.e., a participant paired with a confederate coactor) and investigated how congruency influenced performance. Overall, participants initiated actions faster when they had the same action intention as the coactor (i.e., when participants and the coactor were pursuing the same conceptual goal). Participants' responses were also faster when their and the coactor's movement intentions were directed to the same spatial location, but only when participants had the same action intention as the coactor. These findings suggest that observers use the same representation to implement their own action intentions that they use to infer other people's action intentions and also that a dynamic, multitiered intentional mechanism is involved in the processing of other people's actions.     

The measurement of sharing and cooperation as equity effects and some relationships between them

The initial objective was to determine whether an increase in cooperative responses (minimal cooperation) was also accompanied by an increase in the degree of correspondence in the number of reinforcers of the two subjects (maximal cooperation). Correct matching-to-sample responses of seven pairs of male adolescents were reinforced with money. On each trial, a subject could (1) give the matching-to-sample problem to his coactor (give or cooperative responses), or (2) take the problem for himself (take responses). The first member of the pair to respond made the choice. Correspondence did increase under this procedure as compared to a baseline where problems were distributed randomly. However, the increased correspondence usually resulted from take responses rather than cooperative give responses. This equitable method of problem distribution, designated as sharing, was characterized by the subjects alternately taking problems. The spacing of daily sessions may have been partly responsible for the high degree of correspondence, because correspondence did not increase within the usual number of sessions when the sessions were massed, i.e., all in one day. Daily sessions require cooperative responses, i.e., each subject has to show up each day for the other to earn money, and this dependency upon the coactor's behavior may facilitate some sharing or cooperation to ensure the coactor's attendance.     

Unequal reinforcer magnitudes and relative preference for cooperation in the dyad

College-student subjects, who were paired with a confederate, chose to respond either independently or cooperatively for money reinforcers. The subject's relative preference for cooperation was assessed by a procedure (analogous to the psychophysical method of limits) in which response choice was monitored as reinforcer magnitude for one response mode was systematically varied while the other remained constant. Relative preference for cooperation was assessed when the confederate's payoff for cooperation was greater than the subject's (Experiment I) and when the confederate's payoff for independent responding was less than the subject's (Experiment II). For some subjects, changes in the confederate's reinforcer magnitudes resulted in shifts in relative preference for cooperation, which reduced the earnings differences, even though these preference shifts reduced the subject's absolute earnings. For those subjects for whom within-dyad differences in reinforcer magnitude produced no effect, a changeover button was introduced that allowed the subject to eliminate the payoff difference without reducing her own earnings; some subjects used this changeover button to eliminate earnings differences. Thus, the behavior of subjects varied, in part, as a function of reinforcer magnitudes provided for the confederate.     

The influence of individual versus aggregate social comparison and the presence of others on self-evaluations

In 5 studies, the authors investigated the effects of comparison with an individual versus comparison with the statistical average on self-evaluations of performance and ability. In Studies 1 and 2, participants took a test of lie detection ability and were provided with the average score and the score of an individual coactor. Both types of feedback significantly affected self-evaluations of performance, but only comparison with the coactor significantly affected self-evaluations of ability. Studies 3 and 4 demonstrated that the presence of a coactor moderated the effect of aggregate social comparison on self-evaluations of ability. The results provide preliminary support for the contention that minimizing the impact of comparison with the average is a self-serving strategy that is facilitated by the presence of others.     

Conditioned suppression as a sensitive baseline for social facilitation

The key pecking of pigeons maintained on a variable-interval schedule of food reinforcement was suppressed during occasional presentations of a warning stimulus paired with electric shock. On alternate sessions, a co-actor pigeon was visible in an adjoining chamber where it emitted the same food-reinforced key peck during the warning stimulus that signalled shock for the subject. With no shock and at low shock intensities, where the subject's responding was not suppressed or suppressed only slightly, the co-actor had little effect. At the higher shock intensities, where the subject's responding was reduced by at least 40%, the response rate during the warning stimulus was consistently higher when the co-actor was present. One explanation of these results assumes a special relationship between social stimuli and aversive stimuli in which the presence of another animal reduces emotional reactions and thereby allows operant responses to increase. This was not the case here because the mere presence of the co-actor did not maintain social facilitation. Rather, the present results, taken in conjunction with previous findings, suggest that changes in social and non-social variables which affect the rate of food-reinforced responding may produce proportionately larger changes in responding when that responding is suppressed by aversive stimulation than when it is not.     

Response selection during a joint action task

It has been suggested that a shared task representation is used to predict a coactors' needs and that these predictions influence each coactor's response selection in a joint action task. The authors tested this idea using a joint action task in which participants passed a jug to a confederate under different conditions. They hypothesized that if participants predicted the needs of their coactor and planned their movement according to these predictions, the jug would be passed with the handle available to the confederate. Consistent with this hypothesis, the jug was passed with the handle available on 86% of the trials. This strategy may be adopted to improve the efficiency of the whole task as opposed to each individual's portion of the task.     

Influence of coactors on performance of visually impaired runners

The purpose of this exploratory study was to determine the influence of coactors on the running performance of 13 visually impaired individuals. There was no significant difference for visually impaired sprint runners running alone and with a coactor. The "mere presence" of a coactor was not enough for social facilitation to occur when visual evaluation was not present.     

Psychoanalysis: the transformation of the subject by the spoken word

Psychoanalysis recruits the power of the spoken word to modify the subject's relationship with his or her own unconscious psychic processes. It helps the analysand to reclaim for his or her words the psychic integrity that was lost or never achieved due to the power of defensive dissociation and repression. The psychoanalytic dialogue and the working through mediated by it lead to the elaboration of self-narratives and interpretive understandings, which contribute to the transformation of the subject's self-experience. Such transformation is conditioned by earlier integration of experiences of satisfaction in the context of bodily dialogues and speech with primary objects.     

Effects of competitive reward distribution on auditing and competitive responding

This study allowed subjects to audit each other's responding during a series of competitive contests. Six pairs of female college students competed in 3-min contests in which the competitive response was a knob pull. A sum of money was divided using a proportional distribution or a 100%/0% reward distribution. In the proportional distribution, a subject's proportion of the sum was her proportion of the total number of responses. Also, in every contest either subject could make a response that would end the contest prematurely and give both subjects the same amount: a sum equal to 33% of the competitive total. Each subject could press either or both of two audit buttons that displayed her own and the other's response total for 10 s. Results replicated earlier findings in showing the superiority of the proportional distribution in total number of competitive responses made. No subject audited continuously, and only 1 audited most of the time. Most audits were interpersonal, including both own and other's scores. Auditing typically was more frequent in 100%/0% contests in which subjects were more likely to stop the contest when they were far behind. Winners were more likely to audit than were losers. Competitive response rates increased when the differences revealed by audits were small and decreased when they were large. Overall audit patterns were consistent with the view that feedback as "news" is more often sought when it can lead to improved outcomes.     

Happiness: unlocking the mysteries of psychological wealth,by Ed Diener and Robert Biswas-Diener

No research to date has supported the ‘social contagion’ effect of laughter and smiles in a non-Western context, nor among children. Expressions of positive affect were here compared according to social and non-social conditions among 163 children between the ages of 5–12 while playing in a park in Afghanistan. Independent observers coded laugh and smile responses using published criteria and identified 147 laugh responses and 697 smile responses. Children in the social play condition demonstrated significantly more laughs than children in the non-social play condition, and the number of peer observers present in the social play condition significantly increased the number of participant smile responses, but not laugh responses. Findings supported the idea in Western research that laughter and smiles may function in moderating social relationships and communicating affect. The authors recommend future research to investigate the relationship between positive affect and well-being across cultures, with consideration for practical interventions.     

An infant chimpanzee (Pan troglodytes) follows human gaze

The ability of non-human primates to follow the gaze of other individuals has recently received much attention in comparative cognition. The aim of the present study was to investigate the emergence of this ability in a chimpanzee infant. The infant was trained to look at one of two objects, which an experimenter indicated by one of four different cue conditions: (1) tapping on the target object with a finger; (2) pointing to the target object with a finger; (3) gazing at the target object with head orientation; or (4) glancing at the target object without head orientation. The subject was given food rewards independently of its responses under the first three conditions, so that its responses to the objects were not influenced by the rewards. The glancing condition was tested occasionally, without any reinforcement. By the age of 13 months, the subject showed reliable following responses to the object that was indicated by the various cues, including glancing alone. Furthermore, additional tests clearly showed that the subject's performance was controlled by the "social" properties of the experimenter-given cues but not by the non-social, local-enhancing peripheral properties.

The focusing effect of self-evaluation threat in coaction and social comparison

This article contends that the presence of a coactor leads to a focusing effect whenever this presence represents a threat or a potential threat to self-evaluation. Experiment 1 showed that attentional focusing appears in the presence of an actual (in the case of upward comparison) or potential (in the case of mere coaction) threat to self-evaluation but not in its absence (in the case of downward comparison). Experiments 2 and 3 confirmed that the presence of a coactor affects focusing because the coactor represents a potential threat and showed that introducing a threat in downward comparison can produce a focusing effect. Experiment 4 showed that removing the threat in upward comparison decreases the focusing effect. Experiment 5 confirmed that the effects observed in upward comparison are due to attentional focusing and not to an increase in effort. Contributions to social facilitation, social comparison, and attention research are discussed.     

Need for affiliation,self-esteem,and social distance of black Americans

One hundred three undergraduate men at Howard University were administered a projective measure of the need for affiliation, a self-esteem scale, and a modified version of the Bogardus Social Distance Scale that compared the subject's social distance from his own ethnic group with his social distance from the average of 20 other American ethnic groups. High need for affiliation and high self-esteem were related to small social distance between own and other ethnic groups. Low need for affiliation and low self-esteem interacted to produce the largest social distance. Implications for occupational mobility are discussed.     

Self-discrepancies in clinical depression and social phobia: cognitive structures that underlie emotional disorders?

Previous research indicates that self-discrepancies are cognitive structures that can induce emotional discomfort. The present study compared clinically depressed and social phobic subjects (plus controls) to determine whether different self-discrepancies were associated with the two disorders. In Part 1, it was shown that the depressives possessed the greatest discrepancy between their actual and ideal/own self-states, whereas the social phobics possessed the greatest discrepancy between their actual and ought/other self-states. In a later, ostensibly unrelated study, subjects responded verbally to questions about other people while their mood changes, skin conductance responses, and verbalizations were recorded. The questions included attributes from the subject's ideal and ought self-states that were mismatches with attributes from his or her actual self, as well as mismatch attributes from other subjects. Priming with self-referential mismatches induced momentary syndromes of dejection or agitation (depending on the type of mismatch). The depressives and social phobics showed the greatest increases in dejection and agitation, respectively, according to their dominant self-discrepancy. The results suggest that specific cognitive structures may underlie clinical depression and anxiety.     

Concurrent schedules: short- and long-term effects of reinforcers

Five pigeons were trained on concurrent variable-interval schedules in a switching-key procedure. The overall rate of reinforcement was constant in all conditions, and the ratios of reinforcers obtainable on the two alternatives were varied over seven levels. Each condition remained in effect for 65 sessions, and the last 50 sessions of data from each condition were analyzed. The most recently obtained reinforcer had the largest effect on current preference, but each of the eight previously obtained reinforcers had a small measurable effect. These effects were larger when the reinforcer ratio was more extreme. A longer term effect of reinforcement was also evident, which changed as a function of the reinforcer ratio arranged. More local analyses showed regularities at a reinforcer-by-reinforcer level and large transient movements in preference toward the just-reinforced alternative immediately following reinforcers, followed by a return to stable levels that were related to the reinforcer ratio in effect. The present data suggest that the variables that control choice have both short- and long-term effects and that the short-term effects increased when the reinforcer ratios arranged were more extreme.     

Pointing gestures modulate domestic dogs’ search behavior for hidden objects in a spatial rotation problem

In the spatial domain, domestic dogs are highly inclined to search at the last location where they saw an object disappear and cannot infer that a hidden object has moved imperceptibly from one location to another. In the current study, we examined whether exposure to human social cues modulates dogs’ search behavior for hidden objects. In Experiment 1, twenty dogs were first trained to find an object they saw disappear inside a stationary container in the presence (social group) or absence (non-social group) of pointing gestures. In tests, the containers were rotated 180° around a central axis. The dogs in the non-social group systematically searched at the initial (now incorrect) hiding location, whereas the dogs in the social group chose correctly significantly above chance. In Experiment 2, we tested whether pre-exposure to human pointing has an impact on dogs’ use of gestures. No gestures were given during training and both the social and non-social conditions were administered to each of the ten dogs. In contrast to Experiment 1, the performance of dogs in the social condition dropped significantly and varied substantially from one dog to another. Overall, this study suggests that dogs’ tendency to use human signals is so strong that it even outweighs their spatial bias to search where they saw an object disappear; however, this penchant to use human gestures appears to be dependent on the degree of familiarity of the dog with these signals.     

Can psychoanalysis help us to understand the causes and prevention of violence?

As the most adequate theory of human personality yet created, including our propensity for irrational, self-defeating, and self-destructive behavior patterns, psychoanalysis is in a unique position to help us solve the most serious crisis that the human species has been confronted by at any point in its evolutionary history: the threat to its own survival that is caused by its own behavior, namely the compulsion to engage in violence on the largest scale that its technology makes possible, even when that causes the death of the self as well as of others. This continually expanding behavior pattern, which reduces even genocide to a minor footnote compared with the self-extinction of our whole species, is created not only by “apocalyptic” fundamentalism and terrorism (“suicide bombers”), but also by the increasing and only partially preventable proliferation of thermonuclear weapons to national rulers of questionable sanity, and the apparently unpreventable continuation of industrial/economic policies and practices that will, if not reversed, make our own small planet uninhabitable. What makes people place a higher value on the continuation of these behaviors than they place on their own physical survival (or that of their children)? That is the question to which this article proposes at least the beginnings of an answer: that when a person feels shamed and humiliated to a degree that threatens the survival of that fragile and vulnerable psychological construct called his “self” (or of the religious or cultural group with which his self has identified), he will eagerly sacrifice his body (and other peoples’) in the attempt to, as he sees it, save his soul, i.e. his self and his self-esteem. The question then becomes: what are the social and psychological determinants of overwhelming shame and humiliation, and how can we protect people from being exposed to those conditions, or at least enhance their ability to respond to them in ways that are life-preserving rather than life-destroying?     

Assessment of impulsivity and the development of self-control in students with attention deficit hyperactivity disorder.

We examined a combined approach of manipulating reinforcer dimensions and delay fading to promote the development of self‐control with 3 students diagnosed with attention deficit hyperactivity disorder. First, we administered a brief computer‐based assessment to determine the relative influence of reinforcer rate (R), reinforcer quality (Q), reinforcer immediacy (I), and effort (E) on the students' choices between concurrently presented math problems. During each session, one of these dimensions was placed in direct competition with another dimension (e.g., RvI involving math problem alternatives associated with high‐rate delayed reinforcement vs. low‐rate immediate reinforcement), with all possible pairs of dimensions presented across the six assessment conditions (RvQ, RvI, RvE, QvI, QvE, IvE). The assessment revealed that the choices of all 3 students were most influenced by immediacy of reinforcement, reflecting impulsivity. We then implemented a self‐control training procedure in which reinforcer immediacy competed with another influential dimension (RvI or QvI), and the delay associated with the higher rate or quality reinforcer alternative was progressively increased. The students allocated the majority of their time to the math problem alternatives yielding more frequent (high‐rate) or preferred (high‐quality) reinforcement despite delays of up to 24 hr. Subsequent readministration of portions of the assessment showed that self‐control transferred across untrained dimensions of reinforcement.     

A COMPARISON OF THE EFFECTS OF BRIEF RULES, A TIMER, AND PREFERRED TOYS ON SELF-CONTROL

Some children make impulsive choices (i.e., choose a small but immediate reinforcer over a large but delayed reinforcer). Previous research has shown that delay fading, providing an alternative activity during the delay, teaching participants to repeat a rule during the delay, combining delay fading with an alternative activity, and combining delay fading with a countdown timer are effective for increasing self‐control (i.e., choosing the large but delayed reinforcer over the small but immediate reinforcer). The purpose of the current study was to compare the effects of various interventions in the absence of delay fading (i.e., providing brief rules, providing a countdown timer during the delay, or providing preferred toys during the delay) on self‐control. Results suggested that providing brief rules or a countdown timer during the delay was ineffective for enhancing self‐control. However, providing preferred toys during the delay effectively enhanced self‐control.
