Evaluation apprehension and the social facilitation/inhibition of learning

Sixty female subjects performed a paired-associates learning task either alone or under surveillance by the experimenter, who openly evaluated the subject's performance. To half of the subjects the experimenter described her evaluation as instrumental to the rendering of future help on a similar task; to the remaining half she gave no such promise. Subjects who were evaluated without the expectation of future help performed better than subjects who worked alone when the paired-associates list was easy, but less well when the list was difficult. For both types of list, evaluation with the added promise of future help produced performance no different from that of isolated subjects. Evaluation without the promise of help also produced a higher level of state anxiety than that observed in isolated subjects. The findings were discussed in terms of the effects of evaluation apprehension on the social facilitation and inhibition of learning.     

The nature of equity-restoration: Some approval-seeking considerations

Subjects performed a proofreading task and evaluated its difficulty both beforehand and afterwards. They were overpaid or equitably paid by an experimenter who was or was not directly responsible for the level of pay they received, and who they believed would or would not see their post-test ratings. All subjects knew the experimenter would grade their task performance. Consistent with equity theory, overpaid subjects rated the task as having been more difficult than they had expected and did higher quality work than did equitably paid subjects. However, subjects who thought the experimenter would see their ratings (Aware condition) rated it as more difficult and performed more poorly on it than those who thought she would not see them (Unaware condition). Reported task difficulty increased among overpaid subjects under aware conditions, remained stable among overpaid subjects under unaware conditions, and decreased for equitably paid subjects. These findings suggested that what appears to be “equity-restoration” may be a self-presentation strategy designed to win the experimenter's approval, and that task ratings rather than performance will be used for this purpose when they can be communicated to the experimenter. The experimenter's responsibility for the subject's pay had no effect in the present study.     

Effects of evaluation and coaction on anxiety and anagram performance

In an experiment designed to investigate the effects of experimenter presence on the performance of groups of coacting subjects, male and female subjects worked either alone or in groups of four on a difficult anagrams task. Half the subjects in each of these conditions were observed by the experimenter whereas half worked alone. The results showed that when the experimenter was present, but not when she was absent, coacting subjects experienced higher levels of state anxiety, attempted fewer anagrams, and correctly solved a higher proportion of anagrams attempted than subjects who worked alone. In addition, state anxiety was negatively correlated with the number of anagrams attempted in three of the four treatment groups. The results are discussed in terms of the inhibiting effect of state anxiety on performance and the role of observation in fostering evaluation apprehension in coaction settings.     

The surreptitious observation design: an experimental paradigm for distinguishing artifact from essence in hypnosis

Administered a hypnotic induction and 5 standard hypnotic suggestions twice via audiotape to a group of high-hypnotizable subjects and a group of low-hypnotizable simulators. During the first administration, subjects were led to believe that they were alone. However, their behavior was surreptitiously recorded on videotape and observed on a video monitor. The second administration occurred in the presence of an experimenter who had not been informed of group assignment. When unaware that they were being observed, simulators were significantly less responsive to suggestions than they were when openly observed. In contrast, the behavior of nonsimulating subjects was not affected by the presence of an experimenter. These data indicate that the responses of highly hypnotizable subjects to standard hypnotic suggestions cannot be accounted for in terms of simple compliance with experimental demand.     

Increased performance with increased personal control: A self-presentation interpretation

Past research has found that allowing people a choice of task materials sometimes increases performance on the task. A self-presentation interpretation for this effect was tested and supported in two experiments. In Experiment 1, subjects performed better on a paired-associate learning task when allowed to select some of the words for the test, but only when they believed the experimenter would know of their choice and their performance. In Experiment 2, subjects performed better on what they believed was a cognitive abilities test when allowed to select the test, but again only when they believed their performance would be known by those who were aware of the choice. It was concluded that providing increased control over a task often results in increased concern for self-presentation that may lead to a better performance on the task.     

Temporal effects on attributions for one's own behavior: The role of task outcome

Previous investigations into how attributions for one's own behavior change over time have resulted in surprisingly inconsistent results. Two experiments were conducted to account for these discrepant findings. In Experiment 1 male undergraduates were given feedback indicating that they had done either well or poorly on a skill-assessment test. Half of the subjects believed they were being videotaped when performing the test, half did not. In addition, half of the subjects completed attribution questionnaires immediately after the feedback, whereas half completed the questionnaires 2 or 3 days later. It was found that subjects who felt they had succeeded on the task made attributions that were more dispositional over time and subjects who felt they had failed made attributions that were more situational over time. No effect for the videotape manipulation was found. Experiment 2 replicated the task outcome effect and provided evidence suggesting that the effect was caused by a selective forgetting of unflattering attributions.     

Locomotion, active choice, and spatial memory in children

In two studies, children between 4 and 6 years old were tested on a radial search task requiring nonredundant sampling of eight identically labeled positions in a room. In the training phase (5 days), children made free choices by walking between positions, were passively transported in a pushchair, actively directed their own route from a pushchair, or were led on foot to positions selected by the experimenter. When tested (whether walking or directing while seated in a pushchair), children who had either walked independently or directed the experimenter while being pushed performed competently; those led on foot without spatial choice performed almost as well. Only the children who had neither independent locomotor experience nor autonomous choice performed very poorly. The results are related to neurobiological models of spatial cognition and may have implications for the transportation of children with mobility problems.     

Area-matching strategies used by young children

Across three studies, conditions were varied under which children aged 4–5 years matched the area of a rectangle with a given width (or height) to that of a square. In the first study, subjects observed the rectangle being changed in height from trial to trial and had access to their immediately preceding response. Under these conditions, rectangle width (the dimension under subject control) was a linear decreasing function of rectangle height. This function was interpreted as evidence for a hypothetical addition/subtraction strategy for maintaining equality in area between the comparison rectangle and the standard square. As a test of this hypothesis, in a second experiment the subjects were denied access to their immediately previous response, and in a third study they were also unable to observe the rectangle as it was altered by the experimenter between trials. The purpose of these changes was to remove the information necessary for readily implementing an addition/subtraction strategy. In both studies, area matches seemed to be based on a side-matching strategy, such that subjects matched one dimension of the rectangle to one side of the standard square. It was suggested that young children use different cues or strategies with different variants of the matching task because they do not possess a fixed, specific concept of area.     

Effects of experimenter and mother presence on the attentional performance and activity of hyperactive boys

The attentional performance, activity, and off-task behavior of hyperactive boys with and without conduct problems and normal boys were compared on a cancellation task under three conditions: when performing the task alone, with mother present, and with experimenter present. Results indicated that both the hyperactive groups achieved poorer attentional scores than normal subjects in the alone and mother present conditions, but improved in the experimenter present condition. The performance of the hyperactive boys with conduct problems was particularly affected by this condition. The activity and off-task behavior scores of both the hyperactive groups were higher than controls in all conditions, although the hyperactive boys with conduct problems decreased in off-task behavior when the experimenter was present. Attention and behavior scores were not significantly correlated. The implications of these findings for assessment of hyperactivity, and the role of noncompliance in the attentional behavior of hyperactive children, are discussed.This study is based in part on the first author's Ph.D. thesis in the Department of Psychology, University of Melbourne.     

Duration of failure,causal attributions for failure,and subsequent reactions

Subjects were given a preliminary problem solving task of either short or long duration, and were told that they could shorten the duration of aversive noise bursts by correctly solving the problems. They were then given false feedback that they had done either well or poorly on the problems. Two groups of failing subjects were given information designed to lead them to attribute failure to either lack of ability or a difficult task. Two additional groups received “success” or “failure” feedback without any attributional cues. Failure-induced stress was reported to be greater under short duration conditions than under long duration conditions, and increased to the extent that subjects were led to believe they were personally responsible for failure. Following the preliminary failure period, task performance in the same situation and task performance and persistence in a different situation were assessed. In each case, performance and persistence decreased (a) following short-duration failure when subjects were led to attribute failure to a difficult task, and (b) following long-duration failure when subjects were led to attribute failure to lack of ability. These results are discussed within a framework that emphasizes the role of casual attributions in mediating the effects of failure.     

Symptoms of prosopagnosia in intoxicated subjects.

Two experiments were made to test whether a blood ethanol concentration of about 1 g ethanol per kg blood influences the ability to recognize faces which were shown 24 hours earlier. 18 subjects who saw the faces for the first time when sober and whose task it was to recognize the faces when under the influence of alcohol, recognized the faces significantly less frequently than controls. The controls saw the faces for the first time when sober and their task was to recognize the faces later when also in a sober state. When 20 sober subjects had to recognize faces which they had seen 24 hours earlier under the influence of alcohol, they recognized the faces significantly less frequently than controls. 18 subjects to whom visual forms were shown when under the influence of alcohol and who had to recognize these forms 24 hours later when sober again performed like subjects who had to recognize faces under identical experimental conditions. Subjects who saw the forms, however, in a sober state and who had to recognize these forms when intoxicated performed significantly better than subjects who had to recognize faces under identical experimental conditions. In additional experiments, it was shown that alcohol did not influence ability to compare simultaneously presented faces. Intoxicated subjects' reduced abilities to recognize faces is regarded as a symptom of prosopagnosia since it cannot be explained by a reduced ability to recognize forms or to compare faces.     

Evaluation of a fortuitously reward other

Under the guise of an experiment on gambling decisions, subjects briefly met a confederate of the experimenter, whom they later evaluated. The major hypothesis was that the confederate would be evaluated more favorably by subjects who were told that she had received a fortuitous reward than by control subjects. The hypothesis was confirmed for female subjects only.     

Visuo‐spatial working memory in navigation

Two experiments employed dual task techniques to explore the role of working memory in route learning and subsequent route retrieval. Experiment 1 involved contrasting performance of two groups of volunteers respectively learning a route from a series of map segments or a series of visually presented nonsense words. Both groups performed learning and recognition under articulatory suppression or concurrent spatial tapping. Both concurrent tasks had an overall disruptive effect on each learning task. However, spatial tapping disrupted route recognition rather more than did articulatory suppression, while the nonsense word recognition was impaired more by articulatory suppression than by concurrent spatial tapping. Experiment 2 again used dual task methodology, but explored route learning by asking volunteers to follow the experimenter through the winding streets of a medieval European town centre. Retrieval involved following the same route while the experimenter followed and noted errors in navigation. Overall the results partially replicated those of Experiment 1 in that both concurrent tasks interfered with route learning. However, volunteers with high spatial ability appeared more affected by the concurrent spatial tapping task, whereas low spatial subjects appeared more affected by the concurrent articulatory suppression task. Results are interpreted to suggest that different aspects of working memory are involved in learning a route from a map with a greater emphasis on visuo‐spatial resources, but in tasks set in real environments where many cues of a varied nature are available, only high spatial ability subjects appear to rely heavily upon the visuospatial component of working memory.

Evaluation apprehension and response withholding in solution of anagrams

Sixty male Ss who were classified as high or low scorers on the Sarason Test Anxiety Scale performed a difficult anagrams task either alone, before a passively observing experimenter or in the presence of an experimenter who both observed and evaluated the S's performance. Ss who were high in test anxiety attempted fewer anagrams and had fewer correct solutions in the Evaluated condition than in the Alone condition, but also had a higher proportion of correct solutions out of total attempts. Low test-anxiety Ss did not show variable performance across conditions for any measure. Follow-up studies showed that when Ss were encouraged to attempt partial solutions neither test anxiety nor experimental treatment influenced any of the measures of performance. State anxiety change scores from baseline to post-treatment assessment showed a generally negative correlation between anxiety and number of anagrams attempted. The results indicate that fear of failure engendered by test anxiety and experimenter evaluation caused Ss to withhold responding.     

Attacker's intent and awareness of outcome,impression management,and retaliation

Female Japanese students who were engaged in a calculation task were given electric shocks by a female opponent. The subjects were informed that the opponent had an intent to shock them either severely or mildly. In addition, the opponent's awareness of the outcome of attack was independently manipulated: (1) the subjects received shocks whose intensity corresponded to the opponent's intent, (2) the subjects received shocks whose intensity was inversely proportional to the intensity intended by the opponent and were informed that the opponent did not know about it, or (3) the subjects received reversed shocks as in condition (2), but were further informed that the opponent was well aware of it. An ANOVA of the measure of retaliation in terms of the intensity of shocks delivered to the opponent indicated that (1) the subjects showed more aggression of greater intensity against an opponent who apparently had an aggressive intent than the one who did not, regardless of the actual level of shock intensity; (2) when the severe attack failed, the subjects lowered aggression when the opponent was apparently aware of it as opposed to when she was not; and (3) when the subjects received severe shocks accidentally, they increased aggression when the opponent was apparently aware of it compared to when she was not. These results led us to interpret retaliation as being mediated both by the attribution of intent to the attacker and by self-presentation to the attacker and the experimenter.     

The Impact of Social Comparisons After Failure: The Moderating Effects of Perceived Control

It was proposed that the impact of upward and downward social comparisons on affect and behavior following failure is moderated by perceived control. Subjects who failed an initial test were led to believe that it was either possible or impossible to improve performance on a second test and were exposed to information indicating that others either had done better or had done worse on the first test. As predicted, those who believed that they had little control over their subsequent outcomes and who were exposed to upward comparisons reported greater depressive and hostile affect and persisted less on the second task relative to other subjects. In addition, subjects who had low perceived control showed more interest in additional comparison information when they believed that others had done worse than when they believed that others had done better. Those who believed that they had high control did not show this preference. Findings suggest that upward comparison is debilitating only when accompanied by low perceived control. Further, exposure to downward comparison information may prevent some of the negative effects that have previously been associated with low personal control.     

Causal projection,similarity projection,and coping with threat to self-esteem1

The effectiveness of causal projection and similarity projection in controlling stress associated with threat to self-esteem was investigated. To induce threat to self-esteem, half of the subjects were told that they had done poorly on an important achievement test while the remaining subjects were not told that they had done poorly. The projection strategies were manipulated by encouraging subjects to attribute the cause of their poor performance to the examiner instead of to themselves (causal projection) or to estimate how poorly their friends would have scored on the test had they taken it and not performed well on it (similarity projection). Measures of subjective anxiety, depression, and anger indicated that (a) the testing situation and negative feedback were effective in increasing stress, (b) causal projection was effective in controlling stress, and (c) similarity projection was partially effective in controlling stress. The results provide evidence that causal projection can be effective in controlling stress and also have implications concerning the conditions under which the use of projection will and will not be effective for coping with stress. The importance that situational factors may have on the effectiveness of cognitive coping strategies was emphasized.     

Juvenile domestic pigs (Sus scrofa domestica) use human-given cues in an object choice task

Research on the comprehension of human-given cues by domesticated as well as non-domesticated species has received considerable attention over the last decade. While several species seem to be capable of utilizing these cues, former work with domestic pigs (Sus scrofa domestica) has shown inconclusive results. In this study, we investigated the use of human-given cues in an object choice task by young domestic pigs (N = 17; 7 weeks of age) who had very limited human contact prior to the experiments. Subjects had to choose between two bowls of which only one was baited with a reward. Over the course of five experiments, pigs were able to use proximal and, with some constraints, also distal pointing cues presented in both a dynamic-sustained and in a momentary manner. When the experimenter was pointing from the incorrect bowl towards the correct one, most of the subjects had problems solving the task—indicating that some form of stimulus/local enhancement affected pigs’ decision making. Interestingly, pigs were able to utilize the body and head orientation of a human experimenter to locate the hidden reward but failed to co-orient when head or body orientation of the experimenter was directed into distant space with no bowls present. Control trials ruled out the possibility that other factors (e.g. odour cues) affected subjects’ choice behaviour. Learning during experiments played a minor role and only occurred in three out of twelve test conditions. We conclude that domestic pigs, even at a very young age, are skilful in utilizing various human-given cues in an object choice task—raising the question whether pigs only used stimulus/local enhancement and associative learning processes or whether they were able to comprehend the communicative nature of at least some of these cues.     

Effects of an observer on eating behavior: the induction of "sensible" eating.

An experiment was conducted to investigate the extent of caloric compensation to differential preloading among normally restrained and unrestrained female subjects. Subjects' eating was either explicitly observed or unobserved by the experimenter. Unrestrained eaters compensated appropriately for the preload, whether or not they were observed. Restrained eaters failed to compensate when unobserved , but compensated strongly when observed. A subsequent unobserved eating task revealed that restrained eaters failed to compensate for prior consumption when the observer was withdrawn. Implications for research and therapy are discussed.     

Effector-dependent learning by observation of a finger movement sequence

Can observational learning be effector dependent? In 3 experiments, observers watched a model respond to a 6-item unique sequence in a serial reaction time task. Their sequence knowledge was then compared with that of controls who had performed an unrelated task or observed a model responding to random targets. Observational learning was indicated when the introduction of a new sequence was associated with more reaction time elevation in observers than in controls. The authors found evidence of observational learning only when observers used the finger movement sequence that they observed during training, not when they responded at the same sequence of locations using different digits. Free generation and recognition tests also detected observational learning. These results imply that observational learning can be both explicit and effector dependent.
