Mental Causation and Shoemaker-Realization

Sydney Shoemaker has proposed a new definition of `realization’ and used it to try to explain how mental events can be causes within the framework of a non-reductive physicalism. I argue that it is not actually his notion of realization that is doing the work in his account of mental causation, but rather the assumption that certain physical properties entail mental properties that do not entail them. I also point out how his account relies on certain other controversial assumptions, including analytical filler-functionalism for mental properties, and the assumption that causes must be proportional to their effects. I conclude by pointing out that Shoemaker has provided no explanation of why, on his view, certain physical properties entail mental properties.

Conjunction benefits and costs reveal decision priming for first-order and second-order features

Across two experiments, decision priming was examined for conjunctions composed of first-order or first- and second-order stimulus features. Observers indicated the presence or absence of one or two features in a Gabor stimulus. When a pair of stimulus features differed in their speed of discrimination, responses indicating the presence of a conjunction were faster than those for the single feature for which discrimination was slowest (conjunction benefits). Also, responses indicating the absence of a conjunction were delayed if one of the features was present (conjunction costs). These results show that first- and second-order features can prime decisions about the presence of a conjunction and suggest that the two kinds of signals can be combined at a decision stage after the discrimination of stimulus properties has begun for each system.     

Counting bones: environmental cues that decrease food intake

At an all-you-can eat buffet in a sports bar, it was tested whether people would eat less if they knew how much they had already eaten. 50 graduate students (34 women; M age = 24.1 yr.) were seated at 21 tables randomly assigned to be bussed (leftover wings removed) or unbussed (wings left on table). The 31 students at the bussed tables ate more than those at the unbussed tables (7 wings vs. 5.5 wings), with the effect being stronger for men than women. In distracting eating environments, environmental cues may provide an effective means of reducing consumption. Implications for controlling alcohol intake were also noted.     

Doing philosophy with words

This paper discusses the coverage of ordinary language philosophy in Scott Soames' Philosophical Analysis in the Twentieth Century. After praising the book's virtues, I raise three points where I dissent from Soames' take on the history. First, I suggest that there is more to ordinary language philosophy than the rather implausible version of it that Soames sees to have been destroyed by Grice. Second, I argue that confusions between analyticity, necessity and priority are less important to the ordinary language period than Soames takes them to be. Finally, I claim that Soames' criticisms of Ryle turn in part on attributing reductionist positions to Ryle that Ryle did not hold.

The role of cluster B and C personality disturbance in the course of depression: a prospective study

The association between personality disturbance and depression has been noted consistently. Prospective tests of personality's impact on the course of depression, however, are lacking. In a sample of 159 undergraduates who experienced at least one prospective depressive episode, dimensional scores for clusters B and C personality disturbance were examined as prospective predictors of four indicators of the course of depression: severity, episode duration, symptomatic chronicity and number of episodes. Cluster C personality disturbance, characterized by anxious and fearful features, predicted depression chronicity. Cluster B, characterized by dramatic, emotional and/or erratic features, predicted severity and duration of depression. The findings are discussed in terms of the possible mechanisms underlying the effects of clusters B and C, as well as implications for future research.     

From Nonhuman to Human Mind: What Changed and Why?

ABSTRACT— Two questions regarding the human mind challenge evolutionary theory: (a) What features of human psychology have changed since humans' lineage split from that of the other apes such as chimpanzees and bonobos? And (b) what was the process by which such derived psychological features evolved (e.g., what were the selection pressures)? I review some of the latest research on chimpanzee and canine psychology that allows inferences to be made regarding these questions.     

Implicit–Explicit Relations

ABSTRACT— Mental process and mental experience are not the same thing. The former is the operation of the mind; the latter is the subjective life that emerges from that operation. In social evaluation, implicit and explicit attitudes express this distinction. Although it is clear that they are not the same, how they differ is not. Across content domains, implicit and explicit attitude measures show substantial variability in the strength of correspondence, ranging from near zero to strongly positive. Variation in controllability, intentionality, awareness, or efficiency is thought to differentiate implicit and explicit attitudes. Dual-process theories and empirical evidence for moderating influences of implicit–explicit attitude relations provide a framework for comprehending relations between the operation and the experience of the mind.     

Ageing and autobiographical memory for emotional and neutral events

We investigated age-related effects in recall of emotional and neutral autobiographical memories. Protocols were scored according to episodic and non-episodic detail categories using the Autobiographical Interview. Young adults recalled a greater number of episodic details compared to older adults, whereas older adults recalled more semantic details, replicating previous findings. Both young and older adults' emotional memories contained more overall detail than neutral ones, with the enhancement from emotion-specific to episodic details, but this did not alter the effect of age group on the pattern of episodic and semantic details. However, the age effect on episodic details was attenuated for neutral autobiographical memories. The findings suggest that age differences for emotional autobiographical recollection might reflect a more general pattern of age-related changes in memory, with impaired recall of episodic components and relative sparing of semantic aspects of autobiographical memory in older adults when compared to young adults.     

Disorder-specific Effects of CBT for Anxious and Depressed Youth: A Meta-analysis of Candidate Mediators of Change

The commonalities between anxiety and depression have been discussed before, but few have delineated the potentially different mechanisms through which treatments work for these populations. The current study conducted a comprehensive review of child and adolescent randomized clinical trials that tested cognitive-behavioral therapy (CBT) for anxiety or depression. All studies were required to have assessed both treatment outcomes and at least one theory-specific process target, including behavioral, physiological, cognitive, and coping variables. Using a meta-analytic approach, CBT demonstrated positive treatment gains across anxiety, depression, and general functioning outcomes. CBT for anxiety also produced moderate to large effects across behavioral, physiological, cognitive, and coping processes, with behavioral targets demonstrating potentially the greatest change. CBT for depression produced small effects for cognitive processes but nonsignificant effects for behavioral and coping variables. Findings were generally consistent with CB theory but suggest potentially different mediators in the treatment of anxiety and depression. Results are discussed in terms of implications for mechanisms research, theories of change, and treatment development.
