Combining letter-matching and tone discrimination: Evidence of automatic perceptual and spatial congruity effects

Dual task and priming paradigms were combined to investigate the distinction between automatic and attentional processes. Subjects in two experiments performed a primed letter-matching and a tone discrimination task separately and concurrently. The interval between prime onset and letter pair (SOA) was varied from 50 to 500 msec. Cost-benefit analyses in Experiment 1 indicated that primes that matched target letter pairs began to facilitate performance at an SOA of 150 msec. Primes inhibited performance when they mismatched identical letter pairs at SOA 100. In the dual-task situation, the benefits of priming letter targets were reflected in probe latencies with no evidence of concurrent costs in tone latencies. Experiment 2 revealed that two tasks could be primed simultaneously as effectively as when each was primed alone. Findings are discussed in reference to Posner and Snyder's (1975a, 1975b) two-process theory of priming and the applicability of a secondary task technique.

Zoo Visitors' Affective Responses to Observing Animal Behaviors

ABSTRACT

The opportunity to observe or interact with animals in a zoo is often vital in influencing visitors' positive feelings towards animals and ultimately their conservation behavior. This study explores the relationship between observed animal behavior and zoo visitors' responses. A self-administered questionnaire was completed by 717 visitors across four exhibits (giraffe, lion, cheetah, and red panda) at three zoos (Brookfield Zoo, San Diego Zoo Safari Park, and Central Park Zoo). The questionnaire measured observed animal behaviors and visitors' predispositions, affective responses, and meaning-making at animal exhibits. Multivariate path analyses indicated that up-close encounters with zoo animals, along with observable active animal behaviors, predicted visitors' reported positive affective responses which, in turn, predicted their meaning-making. These findings lend support to the role of positive affect as a mediator between observable animal behaviors and visitor meaning-making. Implications are discussed in relation to achieving both conservation education and animal welfare outcomes.     

Application of the MMPI in Differentiating A.W.O.L. Recidivists from Non-Recidivists

Forty Ss were required to learn two lists of paired associates (an “easy” list and a “difficult” list). A modified anticipation method allowed measures of short-term and long-term retention to be taken. Item difficulty had no effect on STR, but had a large effect upon LTR. The data were interpreted to indicate that two distinct memory mechanisms are involved in the two retention durations.     

A Developmental Explanation For Children’s Motor behavior

Two experiments were conducted to test the application of Pascual-Leone’s (1970) neo-Piagetian theory for explaining children’s acquisition of skill in a curvilinear positioning task. Two groups of children (late pre-operational 6 yr olds and early concrete 8 yr olds) were identified and from each group 10 low M-processors and 10 high M-processors were selected (total n=40) through use of the Children’s Embedded Figures Test. The 6 yr olds were administered 2-and 3-scheme curvilinear positioning tasks while the 8 yr olds performed 3-and 4-scheme tasks. The difference between the two experiments was the nature of the positioning tasks, i.e., one task allowed visual processing of information, while the other did not. Both experiments supported the neo-Piagetian predictions of structural mental space as explaining the developmental nature of motor skill acquisition, and functional mental space as explaining individual differences within stages in children’s performance.     

Retrospective dream components and musical preferences

Retrospective dream components endorsed on the KJP Dream Inventory were correlated with those on the Short Test of Musical Preference for 68 graduate students in counseling psychology (11 men). Among 40 correlations, 6 were significant between preferences for Heavy Metal and Dissociative avoidance dreams (.32), Dreaming that you are dreaming (.40), Dreaming that you have fallen unconscious or asleep (.41), Recurring pleasantness (.31), and Awakening abruptly from a dream (-.31); between preferences for Rap/Hip-Hop and Sexual dreams (.27); and between preferences for Jazz and Recurring pleasantness in dreams (.33). Subjects preferring Classical music reported a higher incidence of Dreams of flying (.33) and rated higher Discontentedness in dreams (-.26). The meaning of these low values awaits research based on personality inventories and full dream reports.
