Stimulus similarity and order as factors in visual short-term memory in nonhuman primates.

The short-term retention of nonhuman primates for a single sample or for two successively presented samples was assessed in four delayed matching-to-sample experiments with delays of .03, 4, 8, 16, and 32 sec. The single sample tasks included one (Experiment 1) or two (Experiment 4) distractor stimuli in the choice set (matching test). In the two successive samples tasks, the animals matched (reconstructed) the order of presentation of two samples with (Experiment 3) and without (Experiment 2) a distractor stimulus. Also, the possible combinations of eight stimuli (four colors and four shapes) were arranged to test the effects of sample set and choice set similarity. Taken together, analyses of the errors indicated that both sample and choice set similarity were significant sources of confusions in delayed matching. Order errors occurred independently of similarity but were a source of forgetting primarily at the longest delays (16 and 32 sec). Two exceptions to the similarity effect (second response errors in Experiment 3 and errors of an inexperienced group in Experiment 4) were observed. Possible reasons for the exceptions and several implications of these findings for theories of short-term memory are discussed.     

Attitudes to Death during the Holocaust: writings from the ghettos

This study explores perspectives on death from ‘within’ the Holocaust, works written in the midst of suffering which were not tempered by or influenced by survival and its traumas. The focus on thinking during the Holocaust will look at two categories of literature written during the Holocaust, which were hidden or distributed by their authors who did not survive. The first involves secular diarist accounts of life in ghettos and the second is the ‘theological’ writing of religious leaders writing for their followers (Rabbi Shapiro'sEsh Kodesh (The Holy Fire) from the Warsaw Ghetto and Rabbi Tiechtall'sEm Habanim Smecha (The Happy Mother of Children) from Budapest). This literature is studied in relation to a number of key questions: how death was recorded; evidence of religious rituals concerning death; how the rituals helped people to cope with death; and the nature of theological debate at the time.     

The use of a visual cue to reduce profanity in a brain injured adult

This study evaluated the use of visual cue to reduce profanity in a brain injured client. The visual cue consisted of placing a piece of paper in front of the client and marking the paper each time the client used profanity. Once profanity was reduced, a maintenance procedure of verbal feedback was introduced which consisted of telling the client how many times he used profanity during a therapy session. A multiple base-line design was used across three settings, and the results showed a decrease in profanity in all three settings.     

Beyond totem and idol,the sexuate other

The author interprets idolatry, totemism, sacrilege and taboo through her theory of sexual difference and her study of Eastern spirituality. She argues that the taboo on spirituality in Western culture has cancelled difference, resulting in our current forms of idolatry. Preserving difference, however, would allow the transcendence of the human other to exist. The task of learning to respect difference is central to human spirituality and spiritual progression. The article is a translation of “La transcendance de l’autre” in Autour d’idôlatrie: figures actuelles de pouvoir et de domination, Ed. Bernard Van Meenen, Publications des Facultés Universitaires Saint-Louis, Brussels: 2003.     

Workaholism, self-esteem, and motives for money

This study examined correlations of workaholism types among 69 male and 86 female undergraduate business students. Three types were considered (Work Addicts, Work Enthusiasts, and Enthusiastic Addicts) using measures developed in 1992 by Spence and Robbins. Correlates included personal demographics, self-esteem, and motives for money. Work Addicts indicated significantly lower self-esteem than both Work Enthusiasts and Enthusiastic Addicts; the workaholism types mentioned above did not differ on motives for money, however.     

Understanding team adaptation: a conceptual analysis and model

This endeavor provides a multidisciplinary, multilevel, and multiphasic conceptualization of team adaptation with theoretical roots in the cognitive, human factors, and industrial-organizational psychology literature. Team adaptation and the emergent nature of adaptive team performance are defined from a multilevel, theoretical standpoint. An input-throughput-output model is advanced to illustrate a series of phases unfolding over time that constitute the core processes and emergent states underlying adaptive team performance and contributing to team adaptation. The cross-level mixed-determinants model highlights team adaptation in a nomological network of lawful relations. Testable propositions, practical implications, and directions for further research in this area are also advanced.     

The effects of delayed reinforcement on variability and repetition of response sequences

Four experiments examined the effects of delays to reinforcement on key peck sequences of pigeons maintained under multiple schedules of contingencies that produced variable or repetitive behavior. In Experiments 1, 2, and 4, in the repeat component only the sequence right-right-left-left earned food, and in the vary component four-response sequences different from the previous 10 earned food. Experiments 1 and 2 examined the effects of nonresetting and resetting delays to reinforcement, respectively. In Experiment 3, in the repeat component sequences had to be the same as one of the previous three, whereas in the vary component sequences had to be different from each of the previous three for food. Experiment 4 compared postreinforcer delays to prereinforcement delays. With immediate reinforcement sequences occurred at a similar rate in the two components, but were less variable in the repeat component. Delays to reinforcement decreased the rate of sequences similarly in both components, but affected variability differently. Variability increased in the repeat component, but was unaffected in the vary component. These effects occurred regardless of the manner in which the delay to reinforcement was programmed or the contingency used to generate repetitive behavior. Furthermore, the effects were unique to prereinforcement delays.     

Workaholism and divorce among Australian psychologists

A study of Australian psychologists compared scores on workaholism components among those who were divorced and those who were married. No differences were found.
