Vocal frequency and person perception: Effects of perceptual salience and nonverbal sensitivity

Previous research has demonstrated that changes in vocal frequency (pitch) influence judgments made about a speaker, although there is some question as to the relative importance of frequency to message content in person perception. Moreover, these studies have failed to examine the possible joint effect of frequency and individual differences in nonverbal sensitivity on person perception. The purpose of the present investigation was to examine the independent and joint effects of vocal frequency, perceptual salience, and nonverbal sensitivity (assessed by the Profile of Nonverbal Sensitivity) on person perception. Participants were assigned to one of nine experimental conditions and were asked to rate two male and two female speakers on seven unipolar adjective scales. The nine conditions were produced by factorially combining three levels each of salience (content, voice, control) and vocal frequency (decreased, increased, unmanipulated). The results of hierarchical multiple regression analyses indicated that variations in frequency did influence evaluative judgments of the speakers (competent, honest, persuasive), but that the magnitude of the influence varied as a function of the participants' levels of nonverbal sensitivity. The analyses, however, yielded no significant effects for participants' affective judgments, nor any significant effects involving perceptual salience.     

Psychoanalytic supervision and the larger truth

If one asks, then, what is the larger truth in supervision and where is it to be found, the answer is that it is to be found in the history and character of the student; in the intersubjective encounter between the student and the supervisor; in the secret use of supervision by the student as he creatively searches for himself. However one chooses to define truth or to speak to a theory of supervision, it is important to note that supervision is not purely an educational activity nor a therapeutic one. It lies somewhere in between and therefore requires some unique theoretical formulations.     

MATHEMATICS AND SELF-ESTEEM: IMPLICATIONS FOR WOMEN'S CAREER CHOICE

The relationship of math participation and success to self-esteem and career goals is examined in a sample of 64 women and 52 men college students at the end of their sophomore year. No gender differences were found in math anxiety or perceptions of the usefulness of mathematics, but women were less likely to select a math-related career goal. Among the men students, math participation and self-assessments of math ability were positively related to more general self-estimates of competence; among women, these variables were not related significantly. Women's choices for math-related careers were more closely associated with scholastic ability and math background than were men's career choices. These results are discussed in the context of societal pressures and supports for men and women in regard to math participation.     

Induction into the workplace: The impact of internships

Some form of work experience or internship ranks high on the list of criteria used by recruiters of college graduates for positions as management trainees. While internships are discussed positively by students, faculty, and recruiters, their evaluation has been faulted as being highly subjective and lacking in the use of controls and psychometric sophistication. This study used an Institutional Cycle design to investigate changes occurring after participation in internships with three cohorts of college age students. Changes were noted in both terminal and instrumental values and in work-specific needs. In the former, changes moved the profiles of the students closer to those of campus recruiters. In the latter, changes moved the students' needs in the direction of characteristics of the job, away from environmental characteristics.     

Integrating vocational interest inventory results and expressed choices

Though many studies have examined the predictive power of expressed choices versus that of measured interests, fewer have been concerned with the relationship between the degree to which choices and interests agree and later persistence in an expressed choice. This study explored that relationship, using longitudinal data for 7706 college students and 1372 employed persons. Four levels of congruence between expressed choice and measured interests were identified. Results indicated that persistence in an expressed choice increases systematically as congruence between choice and interests increases. Implications for counselors are noted.     

A preliminary study of Hare's “Research Scale for the Assessment of Psychopathy” in mentally-abnormal offenders

The abbreviated (15-item) version of Hare's Research Scale for the Assessment of Psychopathy (RSAP) was investigated in a sample of male admissions to Broadmoor Special Hospital (N = 50), along with five MMPI measures relevant to psychopathy (Impulsivity, Sociability, Psychopathic Deviate, Anxiety and Sociopathy). Patients were assigned to one of four clinical diagnostic groups: Personality Disorder, Mixed (personality disorder with schizophrenia), Schizophrenia and Affective Disorder. Results indicated that while both psychopathic groups (Mixed and Personality Disorder) showed high scores on almost all RSAP items, the Affective Disorder group showed low scores on almost all items. Results of a discriminant function analysis indicated that Hare's RSAP was superior to the MMPI measures at discriminating between psychopaths and non-psychopaths. Use of the discriminant function to re-allocate patients to criterion groups showed a high hit rate (94%) for psychopathic patients but a hit rate of only 61% for non-psychopathic patients. Half of the schizophrenic patients were mis-allocated to the psychopathic group. The results support the idea of an affective deficit common to psychopaths and schizophrenics, but suggest that psychopaths additionally show a deficit which may be characterized by a lack of goal-directed behaviour.     

Defense of a Libertarian Interpretation of Descartes' Account of Judgment1

Widespread scholarly agreement has it that Descartes' theory of judgment favors a compatibilist interpretation. This essay explains and rebuts the standard arguments made on behalf of compatibilist readings, while explaining and defending a libertarian interpretation. Along with relevant Fourth Meditation doctrines and texts, my analysis encompasses a much discussed 1645 letter discussing his account. Although some scholars view the letter as departing from the account of the Meditations, I argue that the two works present a consistent view – allowing us to take at face value that the letter purports to elaborate Descartes' intended meaning in the associated Fourth Meditation passage.     

Hiring on vocational interests to simultaneously improve validity and organizational diversity

We discuss how using vocational interests in the selection process can help address the diversity-validity dilemma. First, we point out how incorporating vocational interests as predictors in selection could help to reduce adverse impact. We further suggest that by using optimal predictor weights, one could simultaneously improve validity while enhancing organisational diversity. Finally, the predictive validity of vocational interests arises from their ability to capture the congruence between individuals and occupations, which is a cross-level phenomenon. Thus, when gathering validity evidence for vocational interests, multi-occupation samples should be incorporated into validation efforts.

Thinking disposition,thinking style,and susceptibility to causal illusion predict fake news discriminability

Acceptance of fake news is probably modulated by an intricate interplay of social, cultural, and political factors. In this study, we investigated whether individual-level cognitive factors related to thinking and decision making could influence the tendency to accept fake news. A group of volunteers responded to a COVID19-related fake news discrimination scale as well as to questionnaires assessing their thinking style (reflective vs. intuitive) and thinking disposition (actively open-mindedness). Furthermore, they completed a computerized contingency learning task aimed at measuring their tendency to develop a causal illusion, a cognitive bias leading to perceive causal connections between non-contingent events. More actively open-minded and more reflective individuals presented higher fake news discrimination scores. In addition, those who developed weaker causal illusions in the contingency learning task were also more accurate at differentiating between fake and legitimate news. Actively open-minded thinking was the main contributor in a regression model predicting fake news discrimination.
