Oculomotor programming disturbances in the dementia syndrome

Three types of oculomotor programming disturbances are described in patients with the dementia syndrome. This report describes two of these abnormalities, poorly regulated gaze patterns and a programming type of gaze perseveration. All patients showed poorly regulated gaze patterns in contrast to the normal controls, whereas on the whole only the moderately affected patients showed the programming type of gaze perseveration. The third type of oculomotor programming disturbance is efferent perseveration of gaze (a hypokinetic, "staring" type of gaze pattern) and can be seen with severe dementia. The possible significance of these findings is discussed.     

The role of the church in the community based care of the chronically mentally disabled: Reclaiming an historic ministry

The perplexing circumstance of the chronically mentally disabled in the community poses both a challenging ministry and significant learning opportunity for the church. Historically the church once served as a primary resource in their community life. When care shifted to the hospital in the nineteenth century, chaplains then ministered on behalf of the church. The institutional setting later spawned the clinical training and pastoral care movement, the mental patient an essential teacher and beneficiary. With the locus of care having recently returned to the community, the church can now provide social, pastoral and spiritual resources, collaborate in deinstitutionalization with the mental health delivery system, and return to a ministry of learning with the less resourceful.The Reverend Anderson serves as Chaplain Supervisor, Connecticut Mental Health Center, Box 1842, New Haven, Connecticut 06508, and as a Lecturer in Pastoral Theology at Yale Divinity School.

Relating early child adjustment to infant and parent temperament

The central question at issue was the role of both infant and parent temperament in determining child adjustment at age 4. Within the conceptual framework of the New York Longitudinal Study (NYLS), both infant and parent temperament were assessed. Factor analyses yielded three comparable infant and parent temperament factors: Mood, Energy, and Consistency. Correlations with teacher ratings of child adjustment indicated the most significant relationship to be with the infant girls' Mood factor (comparable to the NYLS high-risk "difficult" infant factor). No infant factors were found to relate to boys' adjustment, while maternal Mood was significant across sexes. Indices of the temperamental similarity within families also revealed sex differences relative to adjustment, with similarity across all family members significantly related to adjustment for girls and boy-father dissimilarity significant for boys. Discussion centered around continuity-discontinuity issues relevant to sex differences.     

The role of dissimulation and social desirability in the measurement of moral reasoning

A series of studies investigating the psychometric and conceptual properties of the Survey of Ethical Attitudes (SEA), a paper-and-pencil measure of moral reasoning, is reported. The results of these studies indicate that the scale is clearly susceptible to the influence of response dissimulation in the form of both role-playing and impression management, and is also confounded with sources of stylistic variance in the form of social desirability. Previous proposals concerning the relationships among moral development, moral reasoning, and personality structure are reviewed in light of these findings, and an alternative conceptualization of the measure in terms of political and social attitudes is offered.     

Outcome predictors in the behavioral treatment of stuttering

The MMPI and subscales of the Stuttering Severity scale were utilized to predict motivation and success in the behavioral treatment of 32 stutterers. Subjects spent a mean of 10 individual sessions in criterion-oriented learning of fluent speech based on speech-muscle relaxation aided by EMG visual biofeedback. Judged motivation and judged success were strongly related to each other and significantly related to MMPI K and Es scores and negatively to F and Sc. Actual success was negatively related to Sc and Pd, completely unrelated to Es, and (if anything) negatively related to K. Results are consistent with previous studies, and show that global judgements of progress were only minimally related to a measure of actual progress.     

Orthography and familiarity effects in word processing

Both orthographic regularity and visual familiarity have been implicated as contributors to the efficiency of processing visually presented words. Our studies sought to determine which of the internal codes representing words in the nervous system are facilitated by these two variables. To do this, sets of letter strings in which orthography and familiarity were factorially combined were used as the basis for physical, phonetic, semantic, and lexical judgments. The data indicated consistent effects of orthography on the activation of all codes. These effects were seen in same-different matching and in judgments of stimulus orientation, which are based on visual codes; in judgments of pronounceability based on phonetic codes; in judgments of meaningfulness based on semantic codes; and in lexical decisions, which are based on phonetic and semantic codes together. Familiarity, on the other hand, had a clear influence on the activation of semantic codes and to a lesser extent affected phonetic codes. Despite previous positive results found in matching letter strings, however, no influence of familiarity occurred in judgments based on visual codes once evidence for criterion shifting was eliminated. Our negative results included direct tests of facilitation in matching acronyms (e.g., FBI) and in matching both regular and irregular strings familiarized by specific training. It now appears that earlier findings of visual familiarity effects may be attributed to response biases resulting from the activation of higher level codes sensitive to familiarity, and to the use of small sets of training stimuli that allowed subjects to induce orthographic-like rules. The results obtained so far with our methods seem to reconcile an inconsistent literature by showing that speeded decisions based on visual codes are most strongly influenced by rule-governed processing mechanisms sensitive to orthographic structure, whereas decisions based on phonetic and semantic codes are affected about equally by rule-governed mechanisms and by stimulus-specific mechanisms sensitive to familiarity. This conclusion may lead to changes in notions of how effective various kinds of visual training are likely to be at different stages in the acquisition of reading skill.     

Increasing Career Center Accessibility for the Blind

To improve career planning services for visually impaired persons, the career center at Florida State University developed a self-directed program. This article describes strategies for making career information materials and resources more accessible to the blind.     

The effect of exercise on the selective performance of an instrumental response

Dogs were used to condition two instrumental reactions—bending of the left or of the right forepaw respectively. In the experimental situation a dish containing food was presented to the dog at a distance but could be drawn close and retained by lifting the forepaw to which (left or right) a lever had been attached. If both paws were simultaneously attached to levers, the dog had to choose between two reactions. Preliminary trials showed a right paw preference in spite of the equal effectiveness (food reinforcement) of the left paw. The aim of this experiment was to alter this right paw preference by a paradigm of differential practice with left paw dominance. The plan was to have ten training sessions followed by one test with choice. According to the probabilities, P_left = 0.8, P_right = 0.2, a random table was used to determine the order of the right-left paw attachments to the levers during training. In all, 1,000 training sessions and 100 tests with choice were carried out in each of three dogs. According to the training program, in every 100 training sessions the left paw had to perform the reaction a total of 80 times and 20 times by the right paw. An absolute alteration in paw preference occurred P_lelt = 1.0) even though both forepaws were equally effective in obtaining food reinforcement on the test trials. The present results indicate that not only the Law of Effect but Exercise is also important in instrumental conditioning.     

Stimulus context and duration discrimination

The ability of human observers to discriminate duration was assessed in two types of tasks: (1) pulse tasks, in which the observer compared the duration of two brief increments in an ongoing sinusoid, and (2) gap tasks, in which the observer compared the duration of two brief interruptions in an ongoing sinusoid. Performance in these tasks was assessed in three different contexts: noise alone, noise plus continuous sinusoids, and noise plus continuous sinusoids chosen to induce a pitch segregation effect. Performance in the pulse task was independent of the changes in context; however, performance in the gap task changed as a function of context condition. There was a large decrement in the observers’ ability to discriminate duration when the stimulus ensemble induced the pitch segregation effect. The results are discussed in terms of the relationship between duration discrimination and stimulus variations which do not carry duration information.
