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.     

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.

The nature of intrusive memories after trauma: the warning signal hypothesis

Individuals who had experienced a range of different traumas were asked to describe the quality and content of their intrusive memories. Visual intrusions were the most common, and thoughts were uncommon. Intrusion quality varied little with type of trauma. Intrusive memories commonly consisted of stimuli that were present immediately before the traumatic event happened or shortly before the moments that had the largest emotional impact (i.e., when the meaning of the event became more traumatic). It is suggested that intrusive memories are about stimuli that through temporal association with the trauma acquired the status of warning signals, i.e., stimuli that if encountered again would indicate impending danger. This explains why intrusive memories are accompanied by a sense of serious current threat. The warning signal hypothesis may be useful in guiding therapists in identifying the moments with the largest emotional impact that will need reprocessing in treatment, and in educating patients about the nature of reexperiencing symptoms.
