Rational Action Entails Rational Desire: A Critical Review of Searle's Rationality in Action1

Abstract

In this paper I contest Searle's thesis that desire-independent reasons for action – ‘reasons that are binding on a rational agent, regardless of desires and dispositions in his motivational set’ – are inherent in the concept of rationality. Following Searle's procedure, I first address his argument that altruistic reasons for action inhere in the concept of rationality, and then examine his argument for his more general thesis. I conclude that a viable theory of rational action would be centered, not on the concept of desire-independent reasons, but rather on the concept of rational desire.     

Effects of aging on voluntary and involuntary shifts of attention

Abstract

This experiment examined adult age differences in the speed and accuracy of voluntary and involuntary shifts of visual attention. Younger and older adults performed two spatial cuing tasks using central cues and abrupt onset peripheral cues presented at stimulus onset asynchronies (SOAs) of 100, 150, 200, 250, and 300 ms. Analyses of the magnitudes of cuing effects revealed a similar time course for younger and older adults in the central cue condition, but not in the peripheral condition. Analyses of the Brinley plot for central cues across cue validity conditions indicated that as much as 93% of the variance could be attributed to age-related general slowing rather than to differential aging of a specific visual orienting mechanism.     

Obtaining guilty knowledge in human intelligence interrogations: Comparing accusatorial and information-gathering approaches with a novel experimental paradigm

Substantial research has assessed interrogations seeking to obtain a criminal confession, and consequently much has been learned regarding the potential problems with confession evidence. However, an increasing focus on counter-terrorism, and therefore intelligence interrogations, reveals an obvious gap in the literature. Intelligence interrogations are primarily focused on collecting information from individuals as opposed to a confession linked to an alleged event, and little of the extant psychological literature can speak directly to such a scenario. The current research developed an experimental paradigm to test interrogation approaches in an intelligence-gathering context, providing a method for gathering empirical data on human intelligence collection. In the first implementation of this paradigm, accusatorial and information-gathering interrogation strategies were tested using a procedure high in psychological realism. Results indicate that an information-gathering approach yields more relevant information than an accusatorial approach and leads to more diagnostic impressions by third party observers.     

Cognitive maps and the hippocampus

Following a familiar route and finding a novel route in a familiar environment depend on different cognitive processes and representations. A recent study by Hartley et al. begins to identity the neural basis of route following and wayfinding in humans. Their study also raises important questions about the functions of the hippocampus.     

Young Adults' Attitudes toward Multiple Role Planning: The Influence of Gender, Career Traditionality, and Marriage Plans

This study examined personal and relationship influences on attitudes toward multiple role planning, specifically preparing to combine work and partnership roles. Survey data were collected from 66 young adult heterosexual couples. Results revealed that marriage plans related positively to knowledge and certainty about multiple role planning. Gender and career traditionality interacted with marriage plans in its influence on commitment to and involvement in multiple roles. Moreover, attitudes toward multiple role planning mediated the association between marriage plans and planning activity for work-family balance. Implications for research and application in multiple role planning are addressed.     

A Test of Objectification Theory in Adolescent Girls

The present study tested the components of the model proposed by Objectification Theory (Fredrickson & Roberts, 1997) in a sample of adolescent girls. Two groups of girls aged between 12 and 16 years (38 girls who currently studied classical ballet, and 45 girls who did not study classical ballet) completed questionnaire measures of self-objectification, body shame, appearance anxiety, and disordered eating. Contrary to prediction, there was no difference between the 2 groups on self-objectification or on any of its proposed consequences. For the total sample, however, the proposed model was largely supported. In particular, body shame and appearance anxiety partially mediated the relationship between self-objectification and disordered eating. It was concluded that Objectification Theory is applicable to adolescents.     

Effects of Exposure to Physique Slides on the Emotional Responses of Men and Women

The purpose of this study was to examine high and low body dissatisfied (BD) men's and women's in-task emotional responses to the acute exposure of sex-specific physique slides of the aesthetic ideal (i.e., ideal slides) and themselves (i.e., self-slides). Participants were 35 male and 30 female university students who reported their immediate in-task emotional responses (i.e., pleasure and arousal) to viewing the self- and ideal slides. It was found that the (a) high BD women reported the least amount of pleasure while viewing the self- and ideal slides; (b) women reported less pleasure while viewing the self-slides than did the men; (c) The high BD group reported less pleasure while viewing the self- vs. the ideal slides than did the low BD group, and (d) the high BD men reported the most arousal of any of the groups while viewing the self- and ideal slides. The differing emotional responses of the men and women and the high and low BD groups to viewing the self- vs. ideal slides are discussed, and future research directions are suggested.     

The sources of skill in seriating cups in children,monkeys and apes

Is a concept of either reversibility or of hierarchical forms of combination necessary for skilled seriation? We examined this question by presenting seriating cups to adult capuchin monkeys and chimpanzees and to 11‐, 16‐ and 21‐month‐old children. Capuchins and chimpanzees consistently created seriated sets with five cups, and placed a sixth cup into a previously seriated set. Children of all three ages created seriated five‐cup sets less consistently than the capuchins and chimpanzees, and were rarely able to place a sixth cup into a seriated set. Twenty‐one‐month‐olds produced more structures containing three or more cups than did the younger age groups, and these children also achieved seriated sets more frequently. Within all participant groups, success at seriating five cups was associated with the frequency of combining three or more cups, regardless of form. The ability to integrate multiple elements in persistent combinatorial activity is sufficient for the emergence of seriation in young children, monkeys and apes. Reliance on particular methods of combination and a concept of reversibility are later refinements that can enhance skilled seriation.     

Object individuation and event mapping: developmental changes in infants’ use of featural information

The present research examined the development of 4.5‐ to 7.5‐month‐old infants’ ability to map different‐features occlusion events using a simplified event‐mapping task. In this task, infants saw a different‐features (i.e. egg‐column) event followed by a display containing either one object or two objects. Experiments 1 and 2 assessed infants’ ability to judge whether the egg‐column event was consistent with a subsequent one‐column display. Experiments 3 and 4 examined infants’ ability to judge whether the objects seen in the egg‐column event and those seen in a subsequent display were consistent in their featural composition. At 7.5 and 5.5 months, but not at 4.5 months, the infants successfully mapped the egg‐column event onto the one‐column display. However, the 7.5‐ and 5.5‐month‐olds differed in whether they mapped the featural properties of those objects. Whereas the 7.5‐month‐olds responded as if they expected to see two specific objects, an egg and a column, in the final display the 5.5‐month‐olds responded as if they simply expected to see ‘two objects’. Additional results revealed, however, that when spatiotemporal information specified the presence of two objects, 5.5‐month‐olds succeeded at tagging the objects as being featurally distinct, although they still failed to attach more specific information about what those differences were. Reasons for why the younger infants had difficulty integrating featural information into their object representations were discussed.
