Long-term proactive interference and novelty enhancement effect in monkey list memory

Serial-probe-recognition (SPR) performance by 2 monkeys deteriorated over several months of training. Three hundred and twenty different items were presented without repetition within a session (trial unique) but were repeated between sessions. The cause of the deterioration was identified as proactive interference (PI) due to repetitive use of items from day to day. Introduction of novel stimuli across days improved performance from 63% to 82% correct (Experiment 1). Tests with only probe items and no list items (Experiment 2) revealed that the monkeys were using a familiar/novel response strategy in combination with a relational strategy (relating the probe item to the list items) to further improve their SPR performance. Intermixing familiar baseline trials and novel transfer trials within a session (Experiment 3) encouraged the subjects to use a relational strategy, and it improved performance on baseline trials as well as on transfer trials. Possible qualitative similarity between the relational strategy and the familiar/novel response strategy is discussed along with theoretical implications of these findings for experiments which have used small number of repeating stimuli within a session.     

Deafness, spelling and rhyme: How spelling supports written word and picture rhyming skills in deaf subjects

Orally trained, congenitally deaf adolescents and hearing, reading-age-matched control subjects made rhyme judgements for pictures and for written words. Hearing children performed the task accurately. By contrast, the deaf group were very poor at rhyme judgement for words and for pictures. For hearing children, word rhyme judgement was more accurate when the words were congruent in their spelling pattern (e.g. bat/hat), less accurate when the spelling pattern of the rhyming words was incongruent (hair/bear). Deaf subjects showed an even more pronounced effect of spelling congruence; their ability to match for rhyme when written words did not share the same spelling pattern was extremely poor. Moreover, spelling congruence predicted deaf subjects' picture rhyming skills.

We conclude that oral training for deaf people does not always permit them to achieve a reliable phonological representation of speech from lip-reading and residual hearing alone. Instead they use the written spelling of the word. This result is not predicted from some previous results that suggest that orally trained deaf people can make direct, spontaneous use of rhyme in the processing of visually presented material.     

A complementary—Empowering model of ministerial leadership

Conclusion In conclusion, we suggest that both contemporary leadership effectiveness theory and a Biblical view of leadership empowering point to what we have called a complementary-empowering model of ministerial leadership. The varying levels of maturity to be found in any congregation require an adaptable leadership style that addresses each member of the congregation at his/her level of maturity and empowers that person for ministry and leadership in the church and community. The skills needed to lead persons at each of the maturity levels are not always given to every minister, thus the complementarity of the Body of Christ provides a variety of gifted leaders who together can empower believers for lives of service to the Body and ministry in the community.     

Men,shame and antisocial behavior: A psychodynamic perspective

This paper discusses the psychosocial factors that contribute to male antisocial behavior. The role of shame and related affects is emphasized. Compensatory defenses associated with these affects are also described. Developmental concepts are reviewed in the light of recent research. Finally, some of the issues involved in doing psychotherapy with this population are discussed, with an emphasis on the value of group therapy.Parts of this paper were presented at the second annual conference onCulture, Race and Ethnicity in Group and Family Therapy which was sponsored by the Eastern Group Psychotherapy Society and New York University and was held in New York City, March 20–22, 1987.     

Altering retrieval demands reverses the picture superiority effect

In Experiment 1 subjects studied a mixed list of pictures and words and then received either a free recall test or a word fragment completion test (e.g.,_yr_mi_forpyramid) on which some fragments corresponded to previously studied items. Free recall of pictures was better than that of words. However, words produced greater priming than did pictures on the fragment completion test, although a small amount of picture priming did occur. Experiments 2 and 3 showed that the picture priming was not due to implicit naming of the pictures during study. In Experiment 4 subjects studied words and pictures and received either the word fragment completion test or a picture fragment identification test in which they had to name degraded pictures. Greater priming was obtained with words in word fragment completion, but greater priming was obtained with pictures on the picture identification test. We conclude that (1) the type of retrieval query determines whether pictures or words will exhibit superior retention, and (2)our results conform to the principle of transfer appropriate processing by which performance on transfer or retention tests benefits to the extent that the tests recapitulate operations used during learning.     

Extension of Heider's ideas to rehabilitation psychology

Fritz Heider received the Psychological Science Gold Medal Award at the 1987 Annual Convention of the American Psychological Association. This article was prepared for the symposium honoring his contributions. It shows the power of his conceptual framework as a basis for systematizing attitude-change attempts involving disability, as well as the need for affirmative action. The analysis involves such concepts as balance, unit-forming factors, sentiment, and ought.     

Effects of semantic priming on visual encoding of pictures

We investigated the effects of semantic priming on initial encoding of briefly presented pictures of objects and scenes. Pictures in four experiments were presented for varying durations and were followed immediately by a mask. In Experiments 1 and 2, pictures of simple objects were either preceded or not preceded by the object's category name (e.g., dog). In Experiment 1 we measured immediate object identification; in Experiment 2 we measured delayed old/new recognition in which targets and distractors were from the same categories. In Experiment 3 naturalistic scenes were either preceded or not preceded by the scene's category name (e.g., supermarket). We measured delayed recognition in which targets and distractors were described by the same category names. In Experiments 1-3, performance was better for primed than for unprimed pictures. Experiment 4 was similar to Experiment 2 in that we measured delayed recognition for simple objects. As in Experiments 1-3, a prime that preceded the object improved subsequent memory performance for the object. However, a prime that followed the object did not affect subsequent performance. Together, these results imply that priming leads to more efficient information acquisition. We offer a picture-processing model that accounts for these results. The model's central assumption is that knowledge of a picture's category (gist) increases the rate at which visual information is acquired from the picture.     

Buildup and release from proactive interference in a rhesus monkey

The potential of the buildup and release from proactive interference (PI) technique in the study of animal categorization was demonstrated with a rhesus monkey. A serial probe recognition task was used with a list of 4 consecutive slide pictures (upper screen) followed by a single probe picture (lower screen). The monkey moved a lever to indicate whether or not the probe was contained in the list. PI built over 40 consecutive trials tested with either flowers or primate faces. PI was released on category change and then built during 40 trials with the second category. The first 2 serial positions showed somewhat greater PI buildup and release, supporting conclusions from human studies that the effects occur primarily in secondary memory. A second experiment provided 2 replications of the main effect and showed through color border changes and elimination of color differences that color was not a critical feature.
