The effects of arm length,size of angle,and spatial separation on Morinaga’s illusion

The effects of arm length, spatial separation between angles, size of angle, and practice on the degree of misalignment in a modified version of Morinaga’s illusion were assessed. Size of angle was manipulated between subjects (n=15/group), whereas arm length, spatial separation, and practice were varied within subjects. Results showed: (1) that as the length of the arm increased, the degree of illusion decreased; (2) that as spatial separation increased, the degree of illusion increased; and (3) an interaction between size of angle and practice. The results were related to Day et al.’s (1982) assimilation theory of Morinaga’s illusion.     

The effects of quantity,complexity, and attentional demand on children’s time perception

An experiment was conducted to investigate the effects of quantity, complexity, and attentional demand on children’s time perception. The appropriateness for children of two models of time perception founded primarily on adult research was examined. These models were the attentional hypothesis and the storage size hypothesis. Ninety-six children, 32 each of 6, 9, and 12 years, observed two and four displays of simple and complex shapes under conditions of higher (matching) or lower (looking) attentional demand. In accord with the attentional model, an inverse relationship was found between attentional demand and children’s time perception. However, in accord with the storage size model, a positive relation was found between quantity and children’s time perception. A developmental trend was also found: younger children were more susceptible to the quantity effect, and older children were more susceptible to the attentional demand effect. Results generalize adult findings to younger children, but the pattern of results is not easily explained solely by either model. Further refinements of either model, or development of a new model that can integrate the two separate findings, appears warranted.     

The effects of problem content,instructions, and verbalization procedure on Wason’s selection task

This study examined various hypotheses for facilitation on Wason’s four-card selection task by means of a factorial experiment. The factors were memory cuing vs. nonmemory cuing content, violation vs. true-false instructions, and verbalization procedure. The results indicated that memory cuing content may be a necessary and sufficient condition for facilitation, but that the amount of facilitation is affected by the type of instructions. Verbalization procedure had no effects, but this may have been due to the subjects’ failure to comply completely with the various verbalization instructions. An explanation of the results that assumes that content and instructions determine the cognitive processing load of the task and hence the solution strategies employed is considered.     

What to do? The effects of discrepancies, incentives, and time on dynamic goal prioritization

This study examined factors that influence the dynamic pursuit of multiple goals over time. As hypothesized, goal-performance discrepancies were significantly related to subsequent time allocation. Greater distance from a given goal resulted in greater time subsequently allocated to that goal. In addition, the incentives offered for goal attainment determined the relative influence of discrepancies for each goal. When the incentives for each goal were equivalent, progress toward each goal exhibited equal influence, with greater time allocated to whichever goal was furthest from completion at the time. However, with an incentive available for only 1 of the 2 goals, time allocation was largely determined by progress toward the rewarded goal. Likewise, when incentives for each task differed in their approach-avoidance framing, progress toward the avoidance-framed goal was a stronger predictor of subsequent allocation than was progress toward the approach-framed goal. Finally, the influence of goal-performance discrepancies differed as a function of the time remaining for goal pursuit. The implications for future work on dynamic goal prioritization and the provision of performance incentives are discussed.

The effects of sex and “masculinity” on person- and space-related perception

A study was conducted to investigate the influence of both sex and sex role upon the perceptual salience of person- and space-related information. It was found that the salience of person-related information was higher for females than males. High-masculinity males found person-related information less salient than any other combined sex and sex-role group. Most importantly, the salience of person-related information was higher for persons who conformed less to their appropriate sex role than those who strongly conformed to their sex role. No sex or sex-role differences were found in the spatial salience measure.     

The effects of emotion on younger and older adults’ monitoring of learning

Age-related differences in memory monitoring appear when people learn emotional words. Namely, younger adults’ judgments of learning (JOLs) are higher for positive than neutral words, whereas older adults’ JOLs do not discriminate between positive versus neutral words. In two experiments, we evaluated whether this age-related difference extends to learning positive versus neutral pictures. We also evaluated the contribution of two dimensions of emotion that may impact younger and older adults’ JOLs: valence and arousal. Younger and older adults studied pictures that were positive or neutral and either high or low in arousal. Participants made immediate JOLs and completed memory tests. In both experiments, the magnitude of older adults’ JOLs was influenced by emotion, and both younger and older adults demonstrated an emotional salience effect on JOLs. As important, the magnitude of participants’ JOLs was influenced by valence, and not arousal. Emotional salience effects were also evident on participants’ free recall, and older adults recalled as many pictures as did younger adults. Taken together, these data suggest that older adults do not have a monitoring deficit when learning positive (vs. neutral) pictures and that emotional salience effects on younger and older adults’ JOLs are produced more by valence than by arousal.     

The beneficial effects of prosocial spending on happiness: work hard,make money,and spend it on others?

Previous research has shown that the way people spend their money is as important to happiness as how much money people earn. Specifically, it has been shown that spending money on others contributes more to an individual’s happiness than spending money on oneself. In the present study, we investigated this effect and examined the role of the money’s origin. Students were randomly assigned either to spend a small amount of money on themselves or to spend the money on others. Moreover, half of the participants received the money as a wage, whereas the other half received the money as a windfall. The results replicated previous research indicating that prosocial spenders report greater happiness than do selfish spenders. However, the happiness effect was unaffected by the source of the money (i.e. wage vs. windfall). Implications for well-being and happiness are discussed.     

Do peers make the place? Conceptual synthesis and meta-analysis of coworker effects on perceptions, attitudes, OCBs, and performance

The authors propose that broad aspects of lateral relationships, conceptualized as coworker support and coworker antagonism, are linked to important individual employee outcomes (role perceptions, work attitudes, withdrawal, and effectiveness) in a framework that synthesizes several theoretical predictions. From meta-analytic tests based on 161 independent samples and 77,954 employees, the authors find support for most of the proposed linkages. Alternative explanations are ruled out, as results hold when controlling for leader influences and mediation processes. The authors also observe differential strengths of coworker influence based on its valence, content, and severity, and on the social intensity of the task environment. The authors conclude with a call for more comprehensive, complex theory and investigation of coworker influences as part of the social environment at work.

Action relations, semantic relations, and familiarity of spatial position in Balint’s syndrome: Crossover effects on perceptual report and on localization

We contrasted effects of the action relationship between objects, relative to effects of semantic relation and familiarity of spatial location, in a patient with Balint’s syndrome. We found enhanced perceptual report of objects placed in the correct colocations for action in comparison with when the objects (1) were placed in incorrect locations for action (Experiment 1), (2) were associatively related (Experiment 2), or (3) fell in familiar locations but were not action related (Experiment 4). In contrast, the ability to localize the objects was affected by whether the objects were in familiar as opposed to unfamiliar locations with respect to one another. Action relations between objects facilitate joint attention to both objects but do not facilitate binding to location. Familiar spatial relations facilitate spatial binding, but do not cue joint attention to the stimuli. Effects of action relation on attention and localization can be dissociated from effects of semantic relationship and familiarity of spatial location on attention and localization.     

Androgen administration to hypogonadal and eugonadal men—effects on measures of sensation seeking,personality and spatial ability

A group of hypogonadal and a group of eugonadal (endocrinologically normal) men complaining of sexual dysfunction were treated with androgens. Psychometric measures of sensation seeking, personality and spatial ability were made before and after treatment. Short-term androgen administration had little effect on these measures. However when the two patient groups were compared while receiving no androgen treatment, the eugonadal men produced significantly higher scores on the Sensation Seeking Scale.     

What causes the spacing effect? Some effects of repetition,duration, and spacing on memory for pictures

Three experiments examined effects of the spacing of repetitions on memory for pictures. In Experiment I, the duration of the first presentation (P(1)) was manipulated, as was P(1)-P(2) spacing. The effect of spacing on judged frequency was independent of P(1) duration. In Experiment II, pictures were given M massed presentations just prior to the P(M)-P(M+1) spacing interval. The form of the spacing curve was independent of M. Neither experiment confirmed the prediction of "overhabituation," derived from the habituation-recovery explanation of the spacing effect. In Experiment III, subjects made both duration and frequency judgments. The duration judgment results were not consistent with the notion that subjects remember multiple massed presentations as single occurrences of especially long duration. Some evidence from Experiments I and III suggests that an interrupted stimulus is recognized better than one that is not interrupted-a finding that, if replicable, would support the habituation-recovery account of the spacing effect.     

Immediate effects of snoezelen? treatment on adult psychiatric patients and community controls

The effectiveness of Snoezelen? multi-sensory stimulation treatment was evaluated with 50 psychiatric patients (25 men, 25 women) and 50 hospital employees (25 men, 25 women). Pre and post-treatment physiological responses (galvanic skin conductance response, heart rate, and percentage blood oxygen) were compared and participants were evaluated post-treatment for perceived psychological benefits with a nine-item questionnaire. Results indicate that participation in a single 20-minute Snoezelen? session had significant and positive physiological effects on both the patient and staff groups. Also, post-treatment participants in both groups did not perceive any change on the dimension reserved-outgoing but felt more sleepy, passive, relaxed, cheerful, focused, optimistic, calm, and comfortable. Consequently, beneficial physiological and psychological Snoezelen? treatment effects were apparent for both patients and controls.     

The effects of readers’ goals on inference generation and memory for texts

We investigated the effects of readers' goals on inference generation and memory for expository text. College students (N = 82) read texts for the purpose of either study or entertainment. On-line inference generation was recorded via think-aloud procedures, and off-line memory was assessed via free recall. Reading goal strongly influenced inferential activity: Readers with a study goal produced more coherence-building (i.e., backward/explanatory and forward/predictive) inferences, whereas readers with an entertainment goal produced more associations and evaluations. These differences were associated with superior memory for the texts in the study condition. The results indicate that inference generation during reading is partly strategic and is influenced systematically by reading purpose. We propose that reading goals influence readers' standards of coherence, which in turn influence the types of inferences that they draw and the final memory representations that they construct.     

The effects of distinctiveness on memory and metamemory for face–name associations

We examined the influence of face and name distinctiveness on memory and metamemory for face–name associations. Four types of monitoring judgements were solicited during encoding and retrieval of face–name pairs that contained distinct or typical faces (Experiment 1) or names (Experiment 2). The beneficial effects of distinctiveness on associative memory were symmetrical between faces and names, such that relative to their typical counterparts, distinct faces enhanced memory for names, and distinct names enhanced memory for faces. These effects were also apparent in metamemory. Estimates of prospective and retrospective memory performance were greater for face–name associations that contained a distinct face or name compared with a typical face or name, regardless of whether the distinct item was a cue or target. Moreover, the predictive validity of prospective monitoring improved with name distinctiveness, whereas the predictive validity of retrospective monitoring improved with facial distinctiveness. Our results indicate that distinctiveness affects not only the strength of the association between a face and a name, but also the ability to monitor that association.     

Influence of modeling on self‐set goals: Direct and mediated effects

Research has shown that seeing another person (i.e., a model) perform at a certain level can influence the goal choice and performance of an observer. This study extended these findings by examining the model's effects on two potential explanatory mediators: expectations of reaching different performance levels and valence at those levels. The moderating effects of observer task experience and self‐esteem were also examined. In a repeated measures design, results showed that model performance influenced observers' goals, task performance, expectancies, and valence ratings. Path analyses indicated that expectancies mediated observational effects on goal choice. Results also indicated significant Model x Trial interactions, with a diminishing effect of model influence as personal experience developed. Results are discussed in terms of mediating effects of expectancies and valences on model influences on goal choice as well as the different weights given to social and personal information.     

Awe’s effects on generosity and helping

It is unclear whether positive emotionality in general, or some specific positive emotions (e.g. other-oriented ones), but not others (e.g. self-oriented and, possibly, stimulus-oriented ones), enhance prosocial thoughts, dispositions, and behavior. We focus here on awe and argue that, although being primarily stimulus-oriented and not necessarily social in its very nature, awe should enhance prosociality for several theoretical reasons. In replicating and extending previous initial research, we found in two online experiments that the induction of awe (video clip or recall), compared to the induction of amusement or a neutral condition, leads to increased prosocial behavioral intentions of generosity (spontaneous sharing of hypothetical gains) and help of a person in need – in hypothetical everyday life situations. Awe’s effect on prosociality was independent from participants’ religiosity (in both experiments) but seemed to be clearer for those in need of such affective stimulation, i.e. less agreeable participants (Experiment 2).     

Individual‐ and group‐level effects of social identification on workplace bullying

A study of 494 employees nested in workgroups from 19 different organizations revealed group identification to be an important factor influencing work-related bullying at both the individual and the group level. Results show that the more employees identified with their group, the less likely they were victims of bullying, which is in line with previous social identity-based analyses of work stress. More importantly, the higher the average level of group identification in the organization, the lower the odds of being a victim versus not being a victim. The latter effect constituted a genuine context effect. These findings redress a neglect of the social bases of workplace bullying and suggest that bullying needs to be understood within a broader perspective of workgroup identities.
