Effects of surface texture on weight perception when lifting objects with a precision grip

In this paper, we show that, when lifting an object using a precision grip with the distal pads of the thumb and index finger at its sides, the perceived weight depends on the object’s surface texture. The smoother the surface texture, the greater the perceived weight. We suggest that a smoother object is judged to be heavier because the grip force, normal to the surface, required to prevent it from slipping is greater. The possibility of there being an influence of surface texture per se is excluded by a second experiment that employed a variant of the precision grip in which the thumb supports the weight of the object from underneath. With the grip oriented in this way, there is no need to match grip force to surface texture and, under these conditions, there is no effect of surface texture on weight perception. In the first two experiments, the test and comparison weights were lifted successively by the same hand. In a third experiment, the effect of surface texture was replicated for sequential lifts made with separate hands. Thus, the effect is not restricted to comparisons made with the same hand.     

On the naming of color words and color patches

Subjects can name color words faster than they can name color patches. To account for that effect, a generic model of naming is described which assumes that words access the mental lexicon directly, whereas color patches do so only indirectly via an initial imaginal or semantic representation. However, Lund (1927) reported that the naming advantage for words disappeared when all the items to be named on a page were the same (i.e., they were blocked). In the present study, three experiments are reported that were designed to provide a clearer empirical definition of Lund’s blocking effect and to ascertain the extent to which it requires a modification of the generic model. The blocked lists had 50 items arranged into 10 blocks, with each block homogeneous with respect to color. The block lengths were either all a predictable length of 5 items or they varied randomly from 1 to 9 items. The data indicated the following: (1) The blocking effect occurred even when the task required a full identification of each item, and (2) the blocking effect was confined to within-block transitions. Blocking seemed to eliminate the word advantage by allowing the subject to re-use the lexical entry used for the immediately prior item, which is consistent with the generic model.     

Heterosexual Therapists Leading Lesbian and Gay Therapy Groups: Therapeutic and Political Realities

The authors describe the thought processes, plans, and reflections of two heterosexual therapists who decided to lead gay and lesbian therapy groups in a university counseling center. The debate regarding the viability of the heterosexual counselor and the gay and lesbian client pair is discussed, as are the practical issues informing and maintaining thegroups. Campus political issues regarding the groups and counselor homophobia are explored.     

Role perceptions: Variations by sex and roles

A Role Perception Scale utilizing a combined projective-objective methodology was developed to assess female and male perceptions of each of three single roles — work, marriage, and parent — and two combined roles — work-marriage and work-parent. Research participants were 134 college students, 88 females and 46 males. Factor analysis of the objective scale, the only part to be scored, resulted in two major orthogonal factors labeled role engagement and competition factors. Sex and role differences for each factor were analyzed using 2×5 split block analysis of variance design with repeated measures. On three out of the five single and combined roles women perceived more engagement than men. In general males perceived roles as more competitive. These sex differences and patterns identified in within-sex analyses across roles are discussed.Parts of this paper were presented at the American Psychological Association Convention, Washington, D.C., September 1976.

Attitudes and duration of unemployment among sixteen-year-old school-leavers

Research is reported which looks at the possibility of using attitude measures to identify, before they leave school, those low-attaining pupils at risk of longer periods of unemployment, and therefore in particular need of support, information and skills. Two independent assessments of attitudes were used: ratings by class teachers, and attitude scales. Findings were largely negative: we cannot predict, through the use of attitude measures alone, which pupils will take longest to find jobs. A variety of other factors influencing duration of unemployment are discussed, together with some implications for careers teaching in schools.     

Evaluating competence of women and men: Effects of marital and parental status and occupational sex-typing

A sample of 160 female and male college students read a completed job application and a letter written by the applicant. The job was in either a feminine or a masculine field. The applicant was described as either female or male, single or married, and having one or no children. Subjects answered seven evaluative questions about the competence of the applicant and the merits of the letter. Women, especially single ones, who applied for a sex-typical job generally were evaluated most favorably. Men, especially single ones, and women who applied for sex-atypical jobs were evaluated least favorably.     

Predicting the Everyday Life Events of Older Adults

Predicting the everyday life events of people is a relatively unexplored topic, although several major theoretical approaches deal with related issues. The dispositional approach would assign a causal role to personality, while the situational approach would locate causation in the person's environment. Variations on these two extreme themes invoke an interactionist interpretation. Beyond this, a genuinely transactional approach focuses on the enduring person-environment relationship established as people deal with major and everyday life events. This study investigated a wide range of predictors of daily positive, negative, and ill-health events over time in a sample of 206 older adults. Results showed that personality variables played only a minor role in predicting daily events, although an interaction between extraversion and social network size was significant. Background demographic variables and the major stressors of recent conjugal bereavement and physical disability played a role in daily event occurrences. Overall, the strongest degree of predictability of events came from the events themselves: The high degree of event stability over time indicated the value of a genuinely transactional model in understanding the occurrence of everyday events.     

Persistence in seminary and in ministry

A follow-up study of 672 seminary students from 14 seminaries who took the Theological School Inventory in 1962 and 574 from 10 seminaries who took it in 1973 investigated factors involved in persistence in seminary and in ministry. Among those found were definiteness of decision, interest in parish ministry, a supportive spouse, unambivalent resolution of the authority problem, good role models in father and ministers. Motivations included redemptive outreach, pastoral care, Christian insight and scholarship, the encouragement of other people and a sense of effectiveness in ministry.Dr. Cardwell is Assistant Professor of Psychology and Counseling at Christian Theological Seminary, 1000 W. 42nd St., Indianapolis, Indiana 46208. This study was the basis for her Ph.D. dissertation, Indiana University, June, 1978. TSI data for the 1973 subjects were made available by Richard A. Hunt, Ph.D., Professor of Psychology, Southern Methodist University, and Director of Ministry Inventories, P.O. Box 8265, Dallas, Texas 75205. TSI data for the 1962 subjects were coded and made available by Edgar W. Mills.

Special credit is due the 16 seminaries who cooperated by furnishing follow-up data.     

Empathy and socialization in first and repeat juvenile offenders and normals

The present study examined empathy and socialization in delinquent and non-delinquent juveniles. From 32 first offenders, 16 repeat offenders, and 19 normals who were administered Hogan's empathy scale and the socialization scale of the California Psychological Inventory, groups of 16 subjects matched on age and race were compared. Results indicated that the three groups did not differ on empathy but that each of the three groups differed on socialization. Results are discussed in terms of potentially identifying recidivists and the efficacy of therapist-trained empathy.     

Quantitative difference in the experience of state-trait anxiety in emotionally disturbed and normal children

In order to investigate the state-trait anxiety distinction in emotionally disturbed and normal children, the responses of 120 emotionally disturbed children and 126 normal children to the State-Trait Anxiety Inventory for Children (Spielberger, 1973) were factor analyzed separately. For the emotionally disturbed group two A-State and two A-Trait factors were found with the A-State factors accounting for significantly more of the variance than did A-Trait factors. For the normal group four A-State and two A-Trait factors were found, but there was not a significant difference between the amount of variance accounted for by A-State and A-Trait factors. Results were discussed as supporting the state-trait distinction and as having several implications for future research on anxiety.
