Age differences in peripheral perceptual processing: a monoptic backward masking investigation

Peripheral processes in vision were investigated in two experiments involving monoptic backward masking with random noise. For young and old subjects, peripheral processing time (represented by stimulus onset asynchrony of target and mask) was characterized as a power function of target energy. Although processing time for both age groups showed a similar rate of decline with increasing target energy, old subjects processed targets more slowly at all energy levels. Results were independent of education, sex, and criterion differences between young and old. Target duration was related to critical interstimulus interval, such that stimulus onset asynchrony between target and mask was approximately constant for a given target energy within each age group. Evidence suggests that peripheral processing begins with target onset and that processing time is best characterized by a power function relating stimulus onset asynchrony of target and mask to target energy.     

Effects of visual familiarity on “same” and “different” decision processes

An experiment was conducted in which subjects matched upper and lower case versions of well-known abbreviations, such as BBC and etc, and meaningless controls. “Same” RT showed a familiarity effect for upper case versions of abbreviations such as BBC and GPO, but not for the lower case versions bbc and gpo. The converse did not occur for abbreviations such as etc, which were thought to occur most frequently in lower case. The “different” RT was inhibited by familiarity, with pairs such as IBM GPO being classified less rapidly than their lower case versions or controls. These effects occurred for subjects instructed to report “No” for “same” displays and “Yes” for “different” displays as well as for subjects given a conventional decision-report assignment. Some implications of these results for an account of the manner in which familiarity affects graphemic comparison processes are considered.     

Comparative evaluation of the Job Club program with welfare recipients

About 1000 WIN welfare clients were selected in five cities: Harlem, New Brunswick, Milwaukee, Wichita, and Tacoma, and half were randomly assigned to the Job Club program. Of the continuing clients, 87% of the Job Club sample obtained jobs vs 59% of the Control sample at the 12-month follow-up and 80 vs 48% at 6 months. The Job Club was more effective in each of the five cities, for men and women, for high school graduates or dropouts, for blacks, whites, and Spanish, for handicapped or nonhandicapped, veterans or nonveterans, the young and the older, and for those required to participate as well as those who volunteered. The jobs obtained by the Job Club clients were comparable to the Control clients' jobs in terms of mean salary, full-time status, and type of job, and were more likely to be enduring, nonsubsidized, and obtained by the job-seeker's own efforts. Job Club members obtained employment in a median of six sessions (mean of 11); 90% obtained jobs within 23 sessions. Follow-up questionnaire data indicated comparable job retention in the two samples but slightly greater advancement and job satisfaction for the Job Club clients. The method appears to assure employment to virtually all participating welfare clients.     

A.R. Luria's role in the development of soviet psychology

Summary A.R. Luria is one of the most outstanding Soviet psychologists. He played a great role in the development of Soviet psychology and in the formulation of psychological problems on the basis of dialectical materialism. Together with L.S. Vygotskij and A.N. Leont'ev, he put forward a theory of the socio-historical genesis of higher, specifically human, mental functions. Luria carried out numerous investigations into the ontogenetic and historical development of these functions, as well as their disturbance with local brain lesions. As the founder, in the Soviet Union, of the new discipline of neuropsychology, he made a very significant contribution to the study of the cerebral mechanisms of mental activity.Originally published in Voprosy Psichologii 28 (4), 106–115 (1978), and translated by E.

Encoding specificity and modality effects in episodic memory

Summary A modified Brown-Peterson paradigm was employed to determine the extent to which proactive interference effects of a sensory nature would influence the occurrence of sensory encoding specificity effects in episodic memory. Subjects presented with an auditory or a visual study list of five to-be-remembered (TBR) words engaged in either an auditory or a visual arithmetic distractor task for 30 s, and then received the first word in the study list as an auditory or visual intralist retrieval cue or received no cue. Presentation of the intralist retrieval cue in the modality of the study list enhanced the effectiveness of the retrieval cue, whereas presentation of the retrieval cue in the modality of the distractor task decreased the effectiveness of the retrieval cue. Sensory encoding specificity effects were largest when the distractor task occurred in the modality opposite to the modality in which both the study list and the retrieval cue were presented.     

Avoiding Counselor Burnout Through Role Renewal

The visual accommodation response during concurrent mental activity

Concurrent mental activity seems to be a significant, nonvisual factor affecting the human accommodation response. Two experiments were conducted to determine the direction and magnitude of this accommodation response. Experiment 1 employed a concurrent, written backwards counting task. Experiment 2 employed a concurrent, mental imagery task of “thinking near” and “thinking far.” In both experiments, the concurrent secondary task effected a cumulative accommodative shift toward the visual far point of from .25 to .75 diopter away from a near (3.0 diopter) target. This accommodative shift was observed only in the presence of a stimulus field and not in open-loop (analogous to empty-field) conditions. In addition, a long-term instability in the open-loop method of obtaining the dark focus was observed. Similarities between this accommodative shift and the pupillary response are noted. The accommodation response is discussed in relationship to both an attention-sharing and an involuntary autonomic response model.

Test for effects of visual and position cues on T-maze learning in toads

This research was concerned with the effects of different classes of cues on the ability of toads (Bufo marinus) to learn an escape task, discrimination learning, in a T-maze. The cues were either a black or white brightness cue, a right or left position cue, or combinations of brightness and position cues. The toads were given a .6-A shock until they made the correct response. Results suggested that toads are capable of learning a discrimination task based on either a position or brightness cue. However, the rate of learning was influenced by strong aversion to the white arm when escaping from an aversive stimulus. No particular preference for either brightness or position cues was found independent of this aversion.
