Cross-cultural differences in tolerance for crowding: fact or fiction?

It is widely believed that cultures vary in their tolerance for crowding. There is, however, little evidence to substantiate this belief, coupled with serious shortcomings in the extant literature. Tolerance for crowding has been confused with cultural differences in personal space preferences along with perceived crowding. Furthermore, the few studies that have examined cultural variability in reactions to crowding have compared subgroup correlations, which is not equivalent to a statistical interaction. Although the authors found a statistical interaction indicating that Asian Americans and Latin Americans differ in the way they perceive crowding in comparison to their fellow Anglo-American and African American citizens, all four ethnic groups suffer similar, negative psychological distress sequelae of high-density housing. These results hold independently of household income.     

Situational moderators of leader reward and punishment behaviors: fact or fiction?

One assumption shared by many contemporary models of leadership is that situational variables moderate the relationships between leader behaviors and subordinate responses. Recently, however, R. J. House and J. L. Baetz (1979 in B. Staw & L. Cummings, Eds., Research in Organizational Behavior (Vol. 1), Greenwich, Connecticut, JAI Press) have suggested that the effects of some leader traits and behaviors may be relatively invariant; that is, have the same effects in a variety of situations. One possible class of leader behaviors which may have relatively consistent effects across situations are those known as leader reward and punishment behaviors. The first goal of the research reported here was to increase our understanding of the relationships between leader contingent and noncontingent reward and punishment behaviors and subordinate responses. Contingent reward behavior was found to have the most pronounced relationships with subordinate performance and satisfaction, followed by noncontingent punishment behavior. Neither leader noncontingent reward nor contingent punishment behavior were found to be related to either subordinate performance or satisfaction, with the exception that noncontingent reward behavior was negatively related to subordinates' satisfaction with work. The second goal of the research was to examine the effects of a variety of potential moderators on the relationships between leader reward and punishment behaviors and subordinate responses. The results of this study suggest that the relationships between leader reward and punishment behaviors and subordinates' performance are relatively free of moderating effects.     

Histrionic personality disorder and antisocial personality disorder: sex-differentiated manifestations of psychopathy?

Little is known about the etiology of histrionic personality disorder (HPD) or its relation to other personality disorders. In this study, we examined whether HPD is etiologically related to psychopathy and more specifically whether HPD and antisocial personality disorder (ASPD) are sex-typed alternative manifestations of psychopathy. In addition, based on Newman's (1987) response modulation hypothesis of psychopathy, we examined the associations between psychopathic, HPD, and ASPD features and performance on laboratory measures of passive avoidance errors and interference effects. Seventy-five live theater actors completed self-report questionnaires and two laboratory measures of response modulation, and peers completed questionnaires concerning the participants' personality disorder features. The results provided weak and inconsistent support for the hypotheses that HPD is a female-typed variant of psychopathy and that ASPD is a male-typed variant of psychopathy. Contrary to previous findings, scores on response modulation tasks were not significantly related to psychopathy, or to either HPD or ASPD. The limitations of this study and possibilities for future research in this area are outlined.     

Depressive Realism: Wiser or Quieter?

The Psychological Record - Depressive realism consists of the lower personal control over uncontrollable events perceived by depressed as compared to nondepressed individuals. In this article, we...     

Loudness adaptation: fact or artifact?

In the present study, the authors tested the hypothesis that contrast effects confound the Ipsilateral Comparison Paradigm (ICP). Bidirectional referents were used in which base tones of 50 or 70 dB alternated with referents of greater or lesser intensity in a 3.5-min listening period. The contrast hypothesis leads to the expectation that the bidirectional referents would produce opposing effects that should nullify time-based loudness changes in the common base tone. Contrary to that expectation, base-tone loudness declined significantly over time in the context of the bidirectional referents, and the loudness of the referents also declined significantly over time. Thus, the results of the study testified to the validity of the ICP as a contrast-free measure of broad-based loudness adaptation.     

Molecular reduction: reality or fiction?

Neurophysiological research suggests our mental life is related to the cellular processes of particular nerves. In the spirit of Occam’s razor, some authors take these connections as reductions of psychological terms and kinds to molecular- biological mechanisms and patterns. Bickle’s ‘intervene cellularly/molecularly and track behaviourally’ reduction is one example of this. Here the mental is being reduced to the physical in two steps. The first is, through genetically altered mammals, to causally alter activity of particular nerve cells, i.e. neurons, at the molecular level and then, under controlled experimental conditions, to use generally-accepted rules of behaviour within psychology to monitor the results of these manipulations. In this article, we argue that Bickle’s case example for molecular reduction, i.e. the reduction of long-term memory to its cellular-molecular mechanisms, cannot support his claims, because it turns out that his chosen molecular pathway is neither a sufficient nor a necessary condition for the memory consolidation switch, and thus, instead of rejecting the multiple realization argument, Bickle’s argument actually speaks in favour of it. Therefore the idea of reductive connections between our mental life and the activity of particular nerves is, at present, still more fiction than reality.     

Eucharist: metaphysical miracle or institutional fact?

Presence as ordinarily understood requires spatio-temporal proximity. If however Christ’s presence in the Eucharist is understood in this way it would take a miracle to secure multiple location and an additional miracle to cover it up so that the presence of Christ where the Eucharist was celebrated made no empirical difference. And, while multiple location is logically possible, such metaphysical miracles—miracles of distinction without difference, which have no empirical import—are problematic. I propose an account of Eucharist according to which Christ is indeed really and objectively present in the religiously required sense, without benefit of metaphysical miracles. According to the proposed account, which draws upon Searle’s discussion of “social ontology” in The Construction of Social Reality and The Making of the Social World, the presence of Christ in the Eucharist is an institutional fact. I argue that such an account satisfies the requirements for a real presence doctrine.     

Auditory agnosia: apperceptive or associative disorder?

Neuropsychological testing of a patient with auditory agnosia showed that certain difficulties in the initial analysis of sounds may be the cause of his inability to understand spoken words and other sounds. Abnormalities included a slow reaction time to brief auditory stimuli (but not to equally brief visual stimuli or to longer auditory stimuli) and the need for approximately 1/4 sec of silence between two tones before the patient was able to hear them as separate. He could identify words and word associations if he was able to view the object whose name or word associate he was hearing. The findings imply that this patient's deficit in comprehending speech was probably apperceptive rather than associative in origin.     

The general factor of personality: Substance or artefact?

While it is now widely recognized that a general factor (GFP) can be extracted from most personality data, this finding has been subject to numerous critiques: (1) that the GFP is an artefact due to socially desirable responding; (2) that it is factorially indeterminate; (3) that it can be more parsimoniously modelled using blended variables; (4) that it shows less genetic variance due to dominance than should be true of a fitness trait; (5) that it correlates more weakly with g than would be predicted from Life History theory; (6) that it cannot be recovered across personality inventories. We present new evidence and argument to show that each of these critiques is open to reasonable doubt.     

Individual differences in preschool children: temperament or personality?

Individual differences among adults have generally been conceptualized in terms of personality theory and traits. In contrast, individual differences among very young children (birth to kindergarten) have generally been conceptualized in terms of temperament theory and traits. The present study compares and contrasts measures of temperament and personality in a sample of preschool children. Temperament traits were assessed with a well‐established measure (the Rothbart CBQ), and a new preschool rating instrument was used to assess personality traits from the five‐factor framework (M5‐PS). Indeed, a key purpose of this study was to further the development of the M5‐PS. Data were gathered on 122 preschool children who were rated by their teachers. Significant correlations were found between the temperament trait Surgency and the personality trait Extraversion, between the temperament trait Negative Affect and the personality trait Neuroticism, and between the temperament trait Effortful Control and the personality trait Conscientiousness. The overall pattern of correlational data suggests that individual differences in preschool children can be adequately described using the five‐factor theory, and that this framework may effectively subsume traditional theories of temperament. Preliminary support for the reliability and validity of the M5‐PS is offered. Copyright © 2010 John Wiley & Sons, Ltd.     

Is avoidant personality disorder more than just social avoidance?

Although social avoidance is a defining feature of avoidant personality disorder (APD), some theorists posit that APD is characterized by a broader pattern of avoidance that extends beyond social situations. This paper describes a series of four studies that examined the different types of nonsocial avoidance hypothesized to characterize APD in three undergraduate student samples and a clinical sample of adults with APD. Overall, the findings revealed low to moderate associations between APD and emotional and novelty avoidance, as well as avoidance of various nonsocial events. The results provide support for contemporary models of APD.     

Frontal lobe dysfunctions in borderline personality disorder? Neuropsychological findings

This study aims to determine whether specific neuropsychological performance impairments in borderline patients can be objectified and whether these findings indicate frontal dysfunctions. Twenty-three patients with borderline personality disorder and 23 normal controls were examined using a neuropsychological test battery to assess intelligence, attentiveness, proneness to interference, learning and memory, as well as planning and problem solving. All subjects filled out standardized questionnaires to assess aggressiveness and impulsiveness in the context of these cognitive performance areas. The neuropsychological test results of the borderline patients were comparable to those of the controls. Although there were no indications of frontal dysfunction of cognitive information processing, inverse correlations were found between the severity of borderline-related personality traits regarding impulsiveness and various areas of cognitive performance. Borderline personality patients show no indications of frontal cognitive dysfunction. Further research is needed to clarify the relationship between impulsiveness and cognitive information processing in borderline personality disorder, including a dimensional approach to personality and personality disorder.     

Borderline and schizotypal personality disorders: mutually exclusive or overlapping?

This article is concerned with one aspect of the validity of DSM-III Axis II diagnoses, namely, the discriminability of borderline and schizotypal disorders. Forty-nine patients diagnosed by DSM-III criteria as borderline, schizotypal, or "mixed" personality disorders completed the Borderline Syndrome Index (BSI), an independent self-report 52-item instrument that has been shown to be reliable and to have discriminative validity. A one-way analysis of variance and a discriminant function analysis were conducted. Our major finding was that there were no significant differences among the groups on the BSI self-report test, although there were differences on clinical grounds. We discuss this in terms of "fuzzy set" theory and prototypic systems of classification.     

Should self-defeating personality disorder be revisited in the DSM?

Self-defeating personality disorder (SDPD) was proposed for consideration in the DSM-III-R, but was eventually removed from the manual because of the lack of evidence to support its validity. Yet, after DSM-IV was published, some studies suggested that SDPD may be a viable diagnosis. The purpose of this study was to evaluate SDPD's viability as a diagnostic category. Consequently, SDPD's internal consistency, comorbidity with other Axis I and II disorders, association with psychosocial impairment, and its ability to predict overall impairment in past, current, and global levels of functioning beyond other personality disorder symptomatology was assessed in 1,200 psychiatric evaluated with the Structured Clinical Interview for DSM-IV Personality (Pfohl, Blum, & Zimmerman, 1997). Cronbach's alpha for SDPD criteria was 0.61, and item-total correlations ranged between 0.22-0.38. There was substantial comorbidity of SDPD with depressive, avoidant, and borderline personality disorders, as well as major depression and anxiety disorders. The SDPD group did not significantly differ from psychiatric controls on multiple measures of psychosocial impairment, global functioning, and suicidality. SDPD did not meaningfully add to the prediction of impairment above and beyond other measures of Axis II pathology. It is concluded that the data do not support the reliability, validity, and utility of the SDPD diagnosis.     

Gender differences in personality: Biological and/or psychological?

The results of three empirical studies are reported in which the hypothesis is tested that differences in personality variables between the morphophenotype sexes can be explained by psychological sex-role orientation variables. Furthermore, it was expected that normative sex-role orientations (measured with the SRO-S and the AWS-S Scales) and gender-related self-concepts (femininity, masculinity, and androgyny measured with a modified BSRI) explain more variance in personality variables than morphophenotype sex. Besides these sex-role orientation variables, test and questionnaire data on verbal fluency, spatial reasoning, self-concept, anxiety, and aggressiveness were obtained in Study I from 50 young adults and their same-sex parents; in Study II, data on verbal fluency, spatial reasoning, self-concept, anxiety, and neuroticism were obtained from 120 university students; and in Study III, data on anxiety, locus of control, and Machiavellianism were obtained from 226 university students. The results confirm both hypotheses for the two aspects of intelligence studied, domain-specific self-concepts, different aspects of anxiety and aggressiveness, neuroticism, powerful others' externality in locus of control, and Machiavellianism. For all these personality variables the effect sizes of the psychological gender variables were larger than those of morphophenotype sex and reached medium to large values.     

AIDS and social exclusion: personality features or adaptive behaviors?

The purpose of this survey is to detect common personality features in people infected with AIDS who have a case history of drug addiction and who live in a situation of social exclusion. The sample comprised 105 male participants from the Autonomous Community of Andalusia, divided into 4 groups: (a) 30 men with AIDS, having an intravenous drug addiction case history and who live in a condition of social exclusion; (b) 30 men with IVDA case history, also living in a situation of social exclusion; (c) 15 men in a social exclusion condition; and (d) 30 men in a condition of social adaptation. The evaluation instruments were an author-designed semi-structured interview and the Multiaxial Clinical Inventory (MCMI-II; Millon, 1987). Although some differences were found, the results indicate that there is no specific personality profile in the "social exclusion" population. People in a condition of social exclusion (AIDS, drug addicts, and poor people) may obtain similar scores in the variables studied, but there is no clear specific personality profile in the excluded population, although there may be certain situations in which the segregated groups present similar behaviors. Furthermore, these behaviors do not always correspond to personality features but are adaptive responses to a harsh and complex reality.
