The effects of parental alcoholism on perception of control and imposter phenomenon

The present study examined the differences in internal and external locus of control and imposter phenomenon among persons with alcoholic and non-alcoholic parents. The subjects were 48 college students and 21 members of local Adult Children of Alcoholic groups. The students were further divided into those with alcoholic parents and non-alcoholic parents. The subjects were administered the following three instruments: the Nowicki-Strickland Internal-External Control Scale for Adults (Nowicki & Duke, 1973), the Imposter Test (Chance & O’Toole, 1987), and a family history survey. Analysis of locus of control scores revealed a highly significant (p<.01) difference for externality, with Adult Children being most external and students with non-alcoholic parents least external. Similarly, internality scores differed significantly (p<.0001), with Adult Children being least, and the non-alcoholic group being most internally oriented. Analysis of variance for imposter phenomenon revealed a significant (p<.05) difference among the three groups, with the Adult Children of Alcoholics group having the highest scores and students with non-alcoholic parents having the lowest. These findings are consistent with the idea that parental alcoholism interferes with nurturing and consistent reinforcement, and with the development of personal adaptability.     

Managed Mental Health: A Primer for Counselors

The mental health service delivery system is experiencing a transformation attendant to rapidly developing cost containment mechanisms. This article reviews various aspects of the new managed mental health care systems and details the gains and losses the various mental health service provider professions may experience depending upon how each responds to the changing demands of alternate service delivery systems. Recommendations are presented regarding how counselors can establish a solid base in the new managed mental health care system.     

Relationship between rigidity-flexibility and cognitive abilities in adulthood

The interrelationship of measures of rigidity-flexibility and of psychometric intelligence is examined. The latent factors of Attitudinal Flexibility, Motor-Cognitive Flexibility, and Psychomotor Speed are derived from the Test of Behavioral Rigidity, and factors of Inductive Reasoning, Spatial Orientation, Verbal Ability, Numeric Ability, Verbal Memory, and Perceptual Speed are derived from the Thurstone Primary Mental Abilities Test and the Educational Testing Service Kit of Factor-Referenced Tests. The data base in this study comes from the fifth wave of the Seattle Longitudinal Study (N = 1,628; age range, 22-95 years). The Rigidity-Flexibility factors were found to be independent of the cognitive domain. Also, longitudinal stability of the factor structure of the rigidity-flexibility domain was confirmed for 837 participants tested in both 1977 and 1984.     

The effect of exercise on depressive symptoms in the moderately depressed elderly

Thirty community-dwelling, moderately depressed elderly were randomly assigned to 1 of 3 interventions: experimenter-accompanied exercise in the form of walking, a social contact control condition, and a wait-list control. Exercise and social contact both resulted in significant reductions in both the total and the psychological subscale of the Beck Depression Inventory (BDI). The exercise condition, however, unlike the control conditions, resulted in decreased somatic symptoms of the BDI. These results indicate that, at least in the short term, exercise has a broader effect compared with control conditions in reducing depressive symptoms in the moderately depressed elderly.     

Issues and options in literacy training

When was the last time you saw a job application with no spelling or grammatical errors? Basic skill deficiencies among people at all levels of business are forcing companies to develop innovative ways of compensating for and correcting the problem. What follows is a summary of literacy training strategies and suggestions for implementation.     

A new typology of health behaviours for personality-health predictions: The case of locus of control

Psychological investigations of the impact of personality on health behaviours have tended to emphasize fine distinctions among personality variables while failing to distinguish among different kinds of behaviours. For example, theoretical treatments of perceived personal control are quite sophisticated; in contrast, only one well-known analysis of health behaviours exists. We propose four categories of health-enhancing behaviours, which take into account contemporary views of the shift in health care from acute and physician-directed actions to long-term and patient-directed efforts. In addition, we suggest that perceived control (we emphasize locus of control because of its generality and parsimony) is an important predictor variable when combined with other factors common to current models of health behaviour.     

Making choice a routine part of mealtimes for persons with profound mental retardation

Despite increased recognition of the importance of providing routine choice opportunities for persons with severe handicaps, this population continues to experience a typical lack of such opportunities. We evaluated a program for increasing the amount of choices made during routine mealtimes by persons with profound mental retardation and minimal communication skills. The choice provision program, involving systematic presentation of alternative food and drink items in a step-wise fashion during the course of the meal, was implemented with three persons in a residential facility. Results indicated that after implementation of the choice program, all three participants made consistently more choices concerning the foods and beverages they consumed relative to baseline. The choice provision program was conducted without extending the amount of time typically allotted to mealtime within the residential setting. Results are discussed in regard to additional research needed to continue developing means of assisting persons with profound mental retardation to exert control over meaningful events in their lives.     

The fear potentiated startle effect

A differential conditioning study examined whether an acoustic startle probe, presented during extinction of an aversively conditioned visual stimulus, potentiated the reflex eyeblink response in humans and whether this potentiation varied with the change in affective valence of the conditioned stimulus. Sixty college students were randomly assigned to view a series of two slides, depicting either unpleasant/highly arousing, unpleasant/moderate arousing, neutral/calm, pleasant/moderate arousing or pleasant/highly arousing scenes and objects (duration: 8 sec). During preconditioning (8 trials) and extinction (24 trials) acoustic startle probes (white noise bursts [50 ms; 95 dBA] were administered during and between slide presentation). During acquisition (16 trials) CS+ was reinforced by an electric shock. Startle response magnitudes significantly increased from preconditioning to extinction and were substantially larger to CS+. Conditioned startle reflex augmentation linearly increased with the pleasantness of the slides. Furthermore, subjects showed a greater post-conditioning increase of judged aversiveness to slides that they had previously reported to be more pleasant, exactly paralleling the startle reflex results.

     

Human adults and human infants show a “perceptual magnet effect” for the prototypes of speech categories,monkeys do not

Many perceptual categories exhibit internal structure in which category prototypes play an important role. In the four experiments reported here, the internal structure of phonetic categories was explored in studies involving adults, infants, and monkeys. In Experiment 1, adults rated the category goodness of 64 variants of the vowel /i/ on a scale from 1 to 7. The results showed that there was a certain location in vowel space where listeners rated the /i/ vowels as best instances, or prototypes. The perceived goodness of Iii vowels declined systematically as stimuli were further removed from the prototypic Iii vowel. Experiment 2 went beyond this initial demonstration and examined the effect of speech prototypes on perception. Either the prototypic or a nonprototypic IM vowel was used as the referent stimulus and adults’ generalization to other members of the category was examined. Results showed that the typicality of the speech stimulus strongly affected perception. When the prototype of the category served as the referent vowel, there was significantly greater generalization to other /i/ vowels, relative to the situation in which the nonprototype served as the referent. The notion of aperceptual magnet was introduced. The prototype of the category functioned like a perceptual magnet for other category members; it assimilated neighboring stimuli, effectively pulling them toward the prototype. In Experiment 3, the ontogenetic origins of the perceptual magnet effect were explored by testing 6-month-old infants. The results showed that infants’ perception of vowels was also strongly affected by speech prototypes. Infants showed significantly greater generalization when the prototype of the vowel category served as the referent; moreover, their responses were highly correlated with those of adults. In Experiment 4, Rhesus monkeys were tested to examine whether or not the prototype’s magnet effect was unique to humans. The animals did not provide any evidence of speech prototypes; they did not exhibit the magnet effect. It is suggested that the internal organization of phonetic categories around prototypic members is an ontogenetically early, species-specific, aspect of the speech code
