Causal Induction From Continuous Event Streams: Evidence For Delay-Induced Attribution Shifts, Marc J. Buehner, Jon May Dec 2009

Causal Induction From Continuous Event Streams: Evidence For Delay-Induced Attribution Shifts, Marc J. Buehner, Jon May

The Journal of Problem Solving

Contemporary theories of Human Causal Induction assume that causal knowledge is inferred from observable contingencies. While this assumption is well supported by empirical results, it fails to consider an important problem-solving aspect of causal induction in real time: In the absence of well structured learning trials, it is not clear whether the effect of interest occurred because of the cause under investigation, or on its own accord. Attributing the effect to either the cause of interest or alternative background causes is an important precursor to induction. We present a new paradigm based on the presentation of continuous event streams, and …


Tactile Learning By A Whip Spider, Phrynus Marginemaculatus C. L. Koch (Arachnida, Amblypygi), Roger D. Santer, Eileen Hebets Apr 2009

Tactile Learning By A Whip Spider, Phrynus Marginemaculatus C. L. Koch (Arachnida, Amblypygi), Roger D. Santer, Eileen Hebets

Eileen Hebets Publications

The ability of animals to learn and remember underpins many behavioral actions and can be crucial for survival in certain contexts, for example in finding and recognizing a habitual refuge. The sensory cues that an animal learns in such situations are to an extent determined by its own sensory specializations. Whip spiders (Arachnida, Amblypygi) are nocturnal and possess uniquely specialized sensory systems that include elongated “antenniform” forelegs specialized for use as chemo- and mechanosensory feelers. We tested the tactile learning abilities of the whip spider Phrynus marginemaculatus in a maze learning task with two tactile cues of different texture—one associated …


The Influence Of Alcohol Advertising On Associative Memory And Consideration Sets, James Charles Smith Jan 2009

The Influence Of Alcohol Advertising On Associative Memory And Consideration Sets, James Charles Smith

LSU Doctoral Dissertations

Survey studies suggest that alcohol advertising influences attitudes and beliefs that promote alcohol use. Strategies from memory research and marketing were used to test the influence of beer advertising found in popular magazines. Effects on preference for alcohol and memory associations between alcohol and the positive outcomes of drinking were measured. One hundred eighty undergraduate women and men viewed 5 ads. A 2 x 2 + 1 (control group) factorial design simultaneously varied ad type (arousing or sedating messages) with processing type (selective attention or elaborative processing). Preferences for alcohol and memory associations did not differ between the control group …
