Semantics and the computational paradigm in cognitive psychology

There is a prevalent notion among cognitive scientists and philosophers of mind that computers are merely formal symbol manipulators, performing the actions they do solely on the basis of the syntactic properties of the symbols they manipulate. This view of computers has allowed some philosophers to divorce semantics from computational explanations. Semantic content, then, becomes something one adds to computational explanations to get psychological explanations. Other philosophers, such as Stephen Stich, have taken a stronger view, advocating doing away with semantics entirely. This paper argues that a correct account of computation requires us to attribute content to computational processes in order to explain which functions are being computed. This entails that computational psychology must countenance mental representations. Since anti-semantic positions are incompatible with computational psychology thus construed, they ought to be rejected. Lastly, I argue that in an important sense, computers are not formal symbol manipulators.     

A Thematic Analysis of Spectator Violence at Sporting Events in North America

This study examines aggravating and mitigating circumstances surrounding spectator fights at stadiums and arenas in North America. Data were collected utilizing a sample of video recordings posted to a popular video-sharing website. A thematic analysis of the data reveals several influences including the role of team allegiances, alcohol use, security presence, and bystander behavior. Potential preventive and reactive interventions to discourage violence in this setting are discussed and evaluated.     

Psychosocial factors in heart surgery: presurgical vulnerability and postsurgical recovery

OBJECTIVE: Distress and low perceived social support were examined as indicators of psychosocial vulnerability in patients about to undergo heart surgery. Design: A total of 550 study patients underwent heart surgeries, including bypass grafting and valve procedures. Psychosocial interviews were conducted about five days before surgery, and biomedical data were obtained from hospital records. MAIN OUTCOME MEASURES: Sociodemographic, personality, religious, and biomedical factors were evaluated as predictors of psychosocial vulnerability, and all five sets of variables were evaluated as contributors to hospital length of stay (LOS). RESULTS: Patients scoring higher on one or more indicator of presurgical psychosocial vulnerability were younger, more likely to be female, less likely to be married, less well educated, lower in dispositional optimism, higher in trait anger, and lower in religiousness. Older age, depression, low support, and low trait anger each showed an independent, prospective association with greater LOS, and several other predictors had prospective relationships with LOS that were statistically mediated by depression or perceived support. CONCLUSION: Evidence that multiple psychosocial factors may influence adaptation to heart surgery has implications for understanding and ameliorating presurgical distress and for improving postsurgical recovery.     

Blood is thicker: moral spillover effects based on kinship

Three empirical studies document the intuitive spillover of moral taint from a person who engages in immoral acts to another individual who is related by ties of blood kinship. In Study 1, participants were more likely to recommend that the biological grandchild of a wrongdoer, compared to a non-biological grandchild, help the descendants of his grandfather's victims. In Study 2, participants were more willing to hold two long-lost identical twins in custody for a crime committed by one twin than to hold two perfect look-alikes for a crime committed by one look-alike. Study 3 provides direct evidence that spillover effects based on blood kinship are manifested in an intuitive sense of moral taint.     

On the number of gods

A god is a cosmic designer-creator. Atheism says the number of gods is 0. But it is hard to defeat the minimal thesis that some possible universe is actualized by some possible god. Monotheists say the number of gods is 1. Yet no degree of perfection can be coherently assigned to any unique god. Lewis says the number of gods is at least the second beth number. Yet polytheists cannot defend an arbitrary plural number of gods. An alternative is that, for every ordinal, there is a god whose perfection is proportional to it. The n-th god actualizes the best universe(s) in the n-th level of an axiological hierarchy of possible universes. Despite its unorthodoxy, ordinal polytheism has many metaphysically attractive features and merits more serious study.     

Disentangling the effects of depression symptoms and adult attachment on emotional disclosure

Individuals with high levels of depression symptoms and individuals with insecure attachment orientations have been shown to limit their use of emotional disclosure as a means of emotion regulation. However, little is known about how depression symptoms and insecure attachment orientations might jointly predict whether individuals engage in emotional disclosure. The authors addressed this question using both inter- and intraindividual approaches. College students (N = 121) completed measures of depression symptoms, adult attachment orientation, and generalized disclosure tendencies. To obtain an intraindividual measure of emotional disclosure, participants also completed an online daily diary in which they rated the intensity of the day's most unpleasant event and their disclosure of that event for 7 days. Results indicated that depression symptoms were negatively related to generalized disclosure tendencies and to intraindividual daily intensity-disclosure slopes. Attachment avoidance was negatively related to both generalized disclosure tendencies and to daily disclosure, and attachment anxiety moderated the relation between daily event intensity and disclosure. The authors discuss the implications for theory and counseling psychology practice.
