A Case for Homogeneity of Personality at the Occupational Level

The forces of attraction–selection–attrition have been hypothesized to create homogeneity of personality within organizations, and vocational choice theory predicts that these forces lead to a ‘modal personality’ within given occupations. This study compared the homogeneity of a set of personality characteristics for 6582 incumbents from eight organizations in eight occupations. The results indicated that (1) the homogeneity hypothesis was supported both within organizations as well as within occupations; and (2) the homogeneity within occupations was higher than that found in organizations.     

Integrity Testing and Job Performance Within High Performance Work Teams: A Short Note

Integrity tests have exhibited robust validity for predicting performance among traditional jobs. However, some organizations have shifted to self-managed work teams and the relationship between integrity and performance within these jobs is untested. One hundred fourteen high performance team members within a single department completed the Hogan Personality Inventory (HPI). The HPI Reliability scale was used as the integrity measure. The subjects' job performance was evaluated by their team leaders. Performance ratings were transformed to equalize ratings across the eight teams. Results indicate that integrity was related to transformed performance ratings (r = .25) within a high performance team environment. Limitations and implications are discussed.     

Perceptions of group homogeneity as a function of social comparison: The mediating role of group identity

Recent research has shown that creating an intergroup context of comparison may influence the outgroup homogeneity effect or even turn it into an ingroup homogeneity effect. In the present study, the aim was to replicate these findings by using overall judgment of similarity instead of the more commonly used dimensional ratings. Further, and more importantly, it was argued that this effect could be explained by an increase in the salience of participants’ group identity. The results showed that context of comparison revealed an effect on both level of group identification and perceptions of relative ingroup and outgroup homogeneity. In line with predictions, participants’ level of group identification seemed to account for the effect of the comparison context on the homogeneity ratings.

Does fantasy-induced sexual arousal habituate?

Habituation in fantasy-induced sexual arousal was assessed by measuring penile circumference and subjective arousal while men engaged in structured sexual fantasy over eight trials, each lasting 2 nun. Arousal levels were higher for men with vivid imagery than for men with non-vivid imagery, but within each group there was no reduction in the level of either physiological or subjective sexual arousal over trials. This result was found not only when Ss engaged in exactly the same fantasy on every trial, but when the erotic strength of fantasy was constant (as established by independent ratings) and the theme of the fantasy varied from trial to trial. In a second experiment 36 trials, each involving 2 min of structured fantasy on a fixed theme, were given. There was again no evidence of habituation in either physiological or subjective arousal. The relationship between these findings and studies concerned with habituation of sexual arousal induced by film, slides, voice, and text is discussed.     

A comparison of two objective measures of sexual arousal of women

The efficacy of two objective measures of sexual arousal of women was compared by simultaneously recording vaginal blood volume by means of a photoplethysmograph and labial temperature by means of a thermistor-clip during and after stimulation by an erotic film. Both measures increased during the stimulation, and they were highly correlated with each other in six of the eight subjects, indicating that both were valid measures of sexual arousal. During the stimulation, labial temperature was significantly correlated with subjective ratings of arousal while vaginal blood volume only approached significance. During the 15-min period following stimulation, the measures neither correlated significantly with subjective ratings nor each other, and both had a tendency not to return to prestimulation levels.     

Empathetic perception of emotional displays in films as a function of hedonic and excitatory state prior to exposure

A film clip depicting a young couple in a dysphoric encounter was seen following one of four film segments that were selected and pretested to effect a factorial variation in (a) hedonic tone (positive, negative) and (b) excitatory potential (low, high). Reactions to the subsequent film were assessed via ratings to test predictions from excitation-transfer theory and to determine sequential effects in hedonically valued experiences. In a first experiment, in which the subsequent film was viewed immediately after the antecedent film, a nearly significant distraction effect of excitation occurred, that is, affective responses to the subsequent film were less intense following high-excitation films than following low-excitation films. In a second experiment, in which the procedure employed in the interval between films was changed to foster close attention to the subsequent film, an excitation-transfer effect was observed, with the dysphoric encounter being perceived as sadder after high-excitation films than after low-excitation films. In both experiments, hedonic-set effects were also observed. The role of cognitive adjustment in excitation transfer was discussed.     

Memory for temporally dynamic scenes

Recognition memory was investigated for individual frames extracted from temporally continuous, visually rich film segments of 5–15 min. Participants viewed a short clip from a film in either a coherent or a jumbled order, followed by a recognition test of studied frames. Foils came either from an earlier or a later part of the film (Experiment 1) or from deleted segments selected from random cuts of varying duration (0.5 to 30?s) within the film itself (Experiment 2). When the foils came from an earlier or later part of the film (Experiment 1), recognition was excellent, with the hit rate far exceeding the false-alarm rate (.78 vs. 18). In Experiment 2, recognition was far worse, with the hit rate (.76) exceeding the false-alarm rate only for foils drawn from the longest cuts (15 and 30?s) and matching the false-alarm rate for the 5?s segments. When the foils were drawn from the briefest cuts (0.5 and 1.0 s), the false-alarm rate exceeded the hit rate. Unexpectedly, jumbling had no effect on recognition in either experiment. These results are consistent with the view that memory for complex visually temporal events is excellent, with the integrity unperturbed by disruption of the global structure of the visual stream. Disruption of memory was observed only when foils were drawn from embedded segments of duration less than 5?s, an outcome consistent with the view that memory at these shortest durations are consolidated with expectations drawn from the previous stream.     

Relative user ratings of MMPI-2 computer-based test interpretations

There are eight commercially available computer-based test interpretations (CBTIs) for the Minnesota Multiphasic Personality Inventory-2 (MMPI-2), of which few have been empirically evaluated. Prospective users of these programs have little scientific data to guide choice of a program. This study compared ratings of these eight CBTIs. Test users were randomly assigned to rate either a single authentic CBTI report on one of their clients or a single CBTI report generated from a modal MMPI-2 profile for their clinical setting. In all, 257 authentic and modal CBTI reports were rated by 41 clinicians on 10 dimensions. Each of the authentic reports received substantially higher ratings than the modal reports, with ratings of perceived accuracy and opinion confirmation best differentiating between authentic and modal reports. Automated Assessment Associates' report received the highest overall ratings; reports published by Western Psychological Services, Pearson Assessments, and the Caldwell Report were also distinguished on one or more ratings dimensions.     

Films for eliciting emotional states in children

Standardized sets of films have been shown to be effective for eliciting emotional states in adults, but no comparable validated stimuli are available for children. We therefore examined the effects of three pre-selected film clips each of 3-min duration in eliciting a pleasant, neutral and unpleasant emotional state in 297 children aged between 6 and 12 years. After the films were presented on a video projector, affective ratings were obtained with the Self-Assessment-Manikin on the emotional dimensions of valence and arousal. Increasing pleasure ratings were observed from the unpleasant to the neutral to the pleasant film. Associated arousal ratings were stronger for the unpleasant and pleasant films compared to the neutral film. Overall, results showed successful elicitation of targeted emotional states only marginally influenced by age, gender or prior experience with the films. The use of these films is therefore suggested for future studies on emotions in children.     

The circle as a model for the interpersonal domain of Swedish trait terms

Swedish interpersonal traits were assumed to have the structure demonstrated by Wiggins for the Interpersonal Adjective Scales in English. Positive and negative interpersonal trait terms were rated for accuracy when describing people. The ratings were used to construct 16 eight-item scales which were ordered relative to two principal components and labelled A to P. The evaluative meaning of each scale item was rated by a second group. The ranks of the mean ratings for the scales followed expectations. The 16 scales were combined into eight scales PA, BC, DE, etc., to NO. From a new group of subjects (N = 159) self-ratings were obtained. The correlations between the eight scales were used to obtain maximum-likelihood estimates of population coefficients of a hypothetical circulant matrix. A circumplex model fitted the data well and the two equally large orthogonal components ordered the PA to NO variables within a circular semantic space. The model was interpreted as a structural representation of basic-level categories for interpersonal attributes of personality in the natural language.     

Attention-Deficit/Hyperactivity symptoms in Icelandic schoolchildren: assessment with the Attention Deficit/Hyperactivity Rating Scale-IV

Four hundred and twenty-seven normal Icelandic children, six and eight years of age, were rated by their parents and three hundred and sixteen children by their teachers with the Teacher and Parent versions of the Attention Deficit/Hyperactivity Disorder Rating Scale-IV (AD/HDRS-IV). For two hundred and sixty-five of the children both parent and teacher ratings were obtained. The factor structures of the AD/HDRS-IV for parents and teachers were in line with theoretical expectations. A Hyperactivity-Impulsivity factor and an Inattention factor were thus well supported. The subscale reliabilities were high. Boys scored higher than girls on all measures and there was a decrease of symptoms with age for boys, as expected. There was evidence of convergent validity for all scales, but discriminant validity of the AD/HDRS-IV subscales is less certain. Generally the instruments seem promising for further research. Some differences are noted in comparison with earlier studies. Thus scores obtained in this study were somewhat lower than those found in American studies, especially for teachers. Also the prevalence of ADHD based on rating scales was lower than in comparable previous studies. The similarity in symptom structure between this and previous studies is emphasized, but the possible role of cultural homogeneity in explaining different results with regard to teachers' ratings of symptoms is suggested.     

Expectancies generated by melodic intervals: Perceptual judgments of melodic continuity

The present study tested quantified predictors based on the bottom-up principles of Narmour’s (1990) implication-realization model of melodic expectancy against continuity ratings collected for a tone that followed a two-tone melodic beginning. Twenty-four subjects (12 musically trained, 12 untrained) were presented with each of eight melodic intervals—two successive tones which they were asked to consider as the beginning of a melody. On each trial, a melodic interval was followed by a third tone, one of the 25 chromatic notes within the range one octave below to one octave above the second tone of the interval. The subjects were asked to rate how well the third tone continued the melody. A series of regression analyses was performed on the continuation ratings, and a final model to account for the variance in the ratings is proposed. Support was found for three of Narmour’s principles and a modified version of a fourth. Support was also found for predictor variables based on the pitch organization of tonal harmonic music. No significant differences between the levels of musical training were encountered.     

A Comparison of Distractors for Controlling Distress in Young Children During Medical Procedures

Distraction is a strategy that has been shown to be effective and safe in the control of pain and distress. We assessed the utility of two simple distraction procedures for reducing children's pain and distress. Three conditions, control, brief film, and short story, were delivered during repeated medical procedures in a randomized sequence to eight young children with cancer. Scores on the Observational Scale of Behavioral Distress (OSBD-R) as well as observer ratings of overall behavioral distress showed that the short story procedure was more effective than either the control condition or the cartoon film. These results argue for the utility of simple parent–child interactive distraction tasks to ameliorate children's procedural distress.     

A MULTIPLE LEVEL INVESTIGATION OF PERSONNEL RATINGS

A multiple levels of analysis approach was used to assess whether job performance and skill importance ratings were based on individual differences, incumbent/supervisor dyadic agreement, group membership, or functional department. Data were collected as part of a managerial training needs analysis conducted at a large gold and silver mining organization. Participants included 140 incumbent managers and their immediate supervisors, who were embedded in 140 incumbent/supervisor dyads, 39 managerial work groups, and eight departments of the organization. Results from Within and Between Analysis (WABA) suggested that (a) incumbent ratings of both performance and skill importance were characterized by individual differences, (b) supervisory ratings of both performance and skill importance were primarily characterized by between-groups (supervisors) differences, (c) matched incumbent-supervisory performance ratings displayed individual differences, and (d) matched incumbent-supervisory importance ratings displayed dyadic agreement (i.e., between-dyads differences). Practical implications of these results for interpreting these and other types of personnel-related data are discussed.     

Components of events and processes

Rips and Estin (1998) provided evidence that mental events such as dreaming are more homogeneous than physical events such as checking out a book; that is, their parts are more difficult to distinguish. In their experiment, participants listed more distinctive properties for the parts of physical events than for the parts of mental events. However, the physicality of stimuli was confounded with temporal aspects. Mental stimuli tended to be processes, and physical stimuli, events. This study tested homogeneity with new stimuli separating out the factors of physicality and aspect. Consistently, both physicality and aspect had significant effects on the perceived homogeneity of activities, as measured by the number of listed parts, the number of distinctive properties of each part, and homogeneity ratings. The study shows that homogeneity is strongly influenced by aspect but that physicality remains a robust factor for homogeneity, even after taking aspect into account.     

回溯式时间记忆特点的实验研究

实验研究在2个月的时间内探索了回溯式时间记忆的特点,实验选取15个影视片断和8个新闻事件,影视片段播放的时间和新闻事件的发生同期,要求被试回忆影视片段和新闻事件的时点、时距和时序。结果表明：（1）在时序上,影视片段时序的准确性高于新闻事件;在时距上,7分钟和15分钟的准确性高于30分钟,7分钟时距倾向于高估,30分钟时距倾向于低估;在时点上,影视片段的准确性高于新闻事件。（2）时点的回溯式记忆受到被试自我卷入程度的影响。（3）回溯式时距估计受到真实时距的长短和延迟时间长短的交互影响。（4）事件序列关系一般倾向于具有网络层次的特征,在无充足思考时间条件下,倾向于具有线形模型的特征。     

Monaural localization following exposure to different segments of acoustic space

Four groups of eight monaural listeners received practice on locating sounds coming from different segments of the horizontal plane prior to a test in which all sounds originated within the same region. An additional eight monaural listeners were given the final localization test without the pretest practice. Knowledge of results was withheld. The main finding was that positive transfer of training was not equally apparent for all groups. That group for which the pretest and test involved the same ear and the same azimuthal positions of loudspeakers performed best. Practice in locating rearwardly positioned sounds did not benefit the localization of frontally positioned sounds even when the same ear was functioning in both situations. Experience in locating sounds from all segments of the horizontal plane appears to be required in order to build up an adequate internal representation of the acoustic surrounds.
