The spacing effect in the learning of word pairs

Following the presentation of a single list of word pairs consisting of a three-letter word on the left and a five-letter word on the right, groups of 64 Ss each were asked to recall the (a) three-letter words, (b) five-letter words, (c) intact pairs, or (d) five-letter words with the three-letter words provided. Two types of repeated pairs were presented, one in which the same three- and five-letter words were repeated together (same pairs) and one in which the same five-letter word was repeated with different three-letter words (different pairs). For half of the Ss in each recall group, the repetitions of a pair containing a given five-letter word were massed (MP); for the other half, the repetitions were distributed (DP). Recall of MP same pairs and the eomponents of these pairs was consistently poorer than that of DP same pairs. Recall of the repeated component of the different pairs was also poorer under MP than under DP. The results were interpreted as supportive of an attenuation-of-attention explanation of the spacing effect.     

A simple turntable for vestibular stimulation of cats by acceleration through a fixed angle with description of a head restraint

An inexpensive turntable for producing uniform angular accelerations for use in vestibular research is described. The table provides semicircular canal stimulation for cats or smaller animals at moderate accelerations above 3 deg sec^?2. A head restraint suitable for use on the table and designed for chronically implanted cats is also described.     

The Heart on the Sleeve and the Secret Self: Estimations of Hidden Emotion in Self and Acquaintances

ABSTRACT This research investigated how estimations of subjectively experienced emotion and estimations of displayed emotion varied with the familiarity of the target person Subjects imagined themselves, a close friend, a moderate friend, or a casual acquaintance in a series of brief affect-eliciting situations, and then estimated the degree to which the designated person would both feel and display specific emotions Subjects consistently estimated that people, including themselves, would feel more emotion than they displayed This discrepancy between experienced feeling and displayed feeling increased as a linear function of familiarity with the person The amount of undisplayed affect–the estimated “secret self”–was generally smallest for a casual acquaintance, greater for a moderate friend, still greater for a close friend, and greatest of all for the self The magnitude of this familiarity effect, however, varied with the social desirability of the emotion If an emotion was socially desirable, subjects estimated that familiar persons would both feel the emotion more and display it more than less familiar others would If an emotion was socially undesirable, subjects also estimated that familiar others would feel it more than unfamiliar others would However, they estimated that familiar and less familiar others would display socially undesirable emotions to about the same degree, and estimated that they themselves would display these emotions significantly less than others Consequently, although subjects always perceived     

Sex Bias in Educational Software: The Effect of Designers' Stereotypes on the Software They Design1

Why is the computer more alluring to boys than it is to girls? One answer to this question is drawn from a social psychological model of human interaction. Social psychological research indicates that the expectations an individual has about another person can shape his or her interaction with that person. We hypothesized that, in a similar manner, the expectations software designers hold about the users of the software they design are central in determining the way the software they design interacts with the user. In order to test this notion, we had 43 educators with programming experience design software for either boys, girls, or students, and found that programs for girls were classifiable as “learning tools,” whereas programs for both boys and students were most like “games.” These differences occur as a function of the designers' expectations of the characteristics of potential users of the program and result in sex stereotyped software. We conclude that it is not the computer, or even the software, that is at the root of the sex bias in software, but the expectations and stereotypes of the designers of the software.     

The relation of trait self-esteem and positive inequity to productivity

The present study explored the relation of trait self-esteem and positive inequity to productivity Subjects worked on proofreading task, and received hourly (rather than piece-rate) compensation that was either greater than (positive inequity condition) or equal to (equity condition) the amount that they deserved The results showed that individuals of high and medium self-esteem were more productive (i e, completed more of the task) in the positive inequity condition than in the equity condition Low self-esteem participants however, were actually less productive (i e, completed less of the task) in the positive inequity than in the equity condition Theoretical implications are discussed     

Layoffs,self-esteem,and survivor guilt: Motivational,affective, and attitudinal consequences

The present study explored the effect of layoffs on the subsequent productivity of “survivors”. All participants performed a proofreading task either after witnessing the dismissal of a co-worker (Layoff condition) or not (No-Layoff condition). Consistent with equity theory, the quantity of workers' performance was greater in the Layoff than in the No-Layoff condition. A Worker Self-Esteem × Layoff interaction effect revealed that the Layoff effect was entirely attributable to the low, rather than the medium or high, self-esteem participants. Additional analyses revealed that the layoff caused participants to (1) experience increased feelings of remorse and (2) develop more negative attitudes toward their co-worker, both of which are also consistent with equity theory. Practical and theoretical implications are discussed.     

Cognitive dissonance and psychotherapy: The role of effort justification in inducing weight loss

The role of effort justification in psychotherapy was examined. It was hypothesized that the effort involved in therapy, plus the conscious decision to undergo that effort, leads to positive therapeutic changes through the reduction of cognitive dissonance. An experiment was conducted in which overweight subjects attempted to lose weight through one of two forms of “effort therapy”. These therapies were bogus in that they were based solely on the expenditure of effort on a series of cognitive tasks that were unrelated to any existing techniques or theory addressing weight loss. One of the therapies called for a high degree of effort while the degree of effort in the second therapy was low. A no-treatment control group was also included. It was predicted that greater weight loss would occur for high-effort than low-effort or control subjects, and that this weight loss would be maintained or increased over time. Results supported these predictions. Over an initial 3-week period, high-effort subjects lost slightly more weight than low-effort subjects or controls. A 6-month follow-up revealed that the effects of effort on weight loss had increased and were highly significant. Reliable differences remained even 1 year after the initial experimental sessions. Possible mechanisms mediating the dissonance effect were discussed, as were several alternative explanations.
