Extending Holland's Hexagon: Procedures,Counseling Applications,and Research

Since its introduction nearly 25 years ago, Holland's (1985) hexagon has remained in skeletal form. The hexagon is used to depict similarities and differences among occupations—but only six general types of occupations. The authors show in this article how to extend the basic concepts embodied in the hexagon. Procedures for locating counselees and occupations on the hexagon are illustrated. These procedures, which are compatible with scores from a wide variety of assessment instruments, can help counselees identify and explore occupational options. The authors also report research on the hexagon locations of 27 career groups.     

A Computational Model of the Simplest Motor Program

A computational procedure (program) is defined to generate control signals for the motoneuron pools of agonist and antagonist muscles that will move a limb segment from one stationary position to another. The program accounts for the ability to move different distances with different inertial loads and for the influence of instructions concerning movement speed and accuracy. These motor commands allow the program to produce EMG patterns as well as force and kinematic trajectories that are consistent with much of the data found in the literature of these movements. The program is premised on the notion that kinematically defined tasks are accomplished by programming commands to the motoneuron pools, based on only a few cognitively recognized kinematic and dynamic features of the task. Most of the features found in EMG and kinematic patterns can be considered consequences of the program's algorithmic procedures rather than specifically planned features of those movements.     

Benefits of humor in reduction of threat-induced anxiety

The benefits of humor in reducing anxiety were investigated in a laboratory study, in which subjects were falsely led to believe that they would receive a shock in 12 min. Participants were 53 undergraduate students with either high or low sense of humor as measured by the Situational Humor Response Questionnaire of Martin and Lefcourt (1984). During the anticipatory period, subjects listened to either a humorous tape, a nonhumorous tape, or no tape. Dependent variables were repeated measures of self-reported anxiety, heart rate, and zygomatic facial activity. Anxiety increased over the anticipatory period, as predicted. A significant interaction between condition and time indicated that subjects from the humor condition consistently rated themselves as less anxious and reported less increase in stress as the shock approached. A three-way interaction concentrating on the final 3 min. indicated a tendency for subjects with low sense of humor to have higher heart rates in the no-tape condition than in the humorous or nonhumorous tape conditions. Analysis for zygomatic activity indicated more smiling by subjects with high sense of humor and by subjects in the humor condition. Also, the humorous tape elicited more smiling by subjects with high sense of humor.     

Content validity: A neglected strategy for developing managerial selection tests?

There is a lack of quick, valid, and cost effective methods for selection of low-and mid-level managerial personnel. Using content-valid methods to develop managerial selection instruments may reap substantial benefits for applicants as well as for the organizations using such tools. To this end, based upon extensive job analysis, a content-valid managerial selection test was developed. Criterion-based validity collected on the new instrument suggested that an instrument developed using content-valid procedures can also show acceptable levels of criterion validity.     

Couples in crisis: Using self report instruments in marriage counseling

Self report inventories are often overlooked as a means of assessment in counseling with couples. A rationale for using self report instruments in working with couples is provided. Case studies are given to illustrate how one such instrument, ENRICH, can be used in developing a treatment strategy, making decisions about referrals, checking treatment progress, and following up on newlyweds.     

Joining with all members of a family system: The rhetoric of antilogic in family therapy dialogue

Family therapists face a significant rhetorical challenge in working with families that disagree about the problematic life-situation which brought them to therapy. Therapists must find a way to join with disagreeing family members and then find a way to engage in a therapeutically useful conversation with them. Thus, they must deal resourcefully with contradictions. This article explores the ways that the Sophistic rhetorical concept of antilogic may be employed in helping therapists join and then engage in a therapeutically useful conversation with families who hold contradictory views concerning the problem that brought them to therapy.The author wishes to thank Ronald Chenail, PhD, Douglas Flemons, PhD, and Shelly Green, PhD, for their assistance in the development of this project.     

Instructions and decision times of size-constancy responses

The current study investigated the effect of instructions and stimulus discriminability on size-constancy responses and decision times in a task allowing separate evaluation of the effects of instructions and of dimensional choices by the subjects in the size-constancy task. Objective, perspective, or distance matches were influenced both by the instructions given the subject and by the relative discriminability of the stimuli in each dimension, so that subjects did not always successfully follow their instructions. Decision times were found to be fastest with perspective rather than objective or apparent instructions, but times taken to produce objective and perspective matches did not differ. Apparently, both objective and perspective judgments are available to the perceiver before a response is made, but instructions affect postperceptual response times.
