Conditions Under Which a Bogus Pipeline Procedure Enhances the Validity of Self-Reported Cigarette Smoking: A Meta-Analytic Review1

A meta-analysis was conducted to test whether the use of self-report measures within the bogus pipeline (BPL) paradigm yields more valid responses than the use of self-report measures alone for assessing cigarette smoking behavior. The meta-analytic results indicate that, overall, a BPL condition resulted in a larger proportion of subjects reporting that they are frequent smokers, as compared to a self-report measure only (no pipeline) condition. Tests of categorical models indicate that the enhanced validity of self-reports within the BPL paradigm is moderated by the following variables: (a) type of BPL presentation employed, (b) type of self-report measure to which the BPL technique is compared, and (c) whether most participants are smokers (as indicated by a biochemical marker).     

NEURONAL CODING OF SERIAL ORDER:

Abstract— How does the brain create rule-governed sequences of behavior? An answer to this question may come from a surprising source: the neostriatum (caudate nucleus and putamen), Traditionally, the neostriatum has been considered pun of the brain's motor system, but its contribution to the preparation or execution of movement is recognized generally to concern high-level motor functions. Recent work implicates the neostriatum in disorders of sequential action and thought, as in the repetition of thoughts or habits in human obsessive-compulsive disorder and movements or speech in Tourette's syndrome. Yet there is no direct evidence to support the idea that the neostriatum controls sequences of behavior. Using ethological and neurophysiological techniques to study neural activity in the rat neoslriatum during syntactic grooming sequences, we found that neuronal activity in the anterolateral neostriatum depended on the execution of syntactic sequences of grooming actions. The individual grooming movements themselves did not activate the neoslriatum; activation was determined by the syntactic sequence in which grooming movements were performed. These data provide the first direct evidence that the neoslriatum coordinates the control of rule-governed behavioral sequences.     

The multiple vigilance test

The multiple vigilance test is a 30-min signal detection task designed to assess performance. Sixty target and 180 nontarget stimuli are presented with random interstimulus intervals ranging from 4 to 11 sec. Subjects respond by pressing the spacebar (or microswitch in an alternate version of the program) when they see the masking pattern transformed into the target. This vigilance test is used in conjunction with measures of physiological sleepiness (Multiple Sleep Latency Test) and subjective sleepiness (Stanford Sleepiness Scale). This behavioral information concerning manifest sleepiness provides a more complete picture of a subject’s state of alertness. The assessment of vigilance during long, monotonous, nonstimulating tasks is clinically important in patients with disorders of sleep and arousal.     

Effects of physical threat and ego threat on eating behavior

Restrained and unrestrained subjects were subjected to one of three distress manipulations prior to an ad lib taste task. The physical fear threat (anticipated electric shock) significantly decreased unrestrained subjects' eating and slightly increased restrained subjects' eating. Both ego threats (failure at an easy task or anticipating having to give a speech in front of an evaluative audience) significantly increased restrained subjects' eating but did not significantly suppress unrestrained subjects' eating. This pattern supports the proposition that physical fear differs from more general dysphoria in its effects on eating, perhaps because of the divergent effects of these two types of distress on eating control mechanisms, which in turn differ in restrained and unrestrained eaters.     

The Icarus flight of speculation: Philosophers' vices as perceived by nineteenth-century historians and physicists

Why did nineteenth-century German historians and physicists habitually warn against vices that they believed philosophers in particular embodied: speculation, absence of common sense, and excessive systematizing? Drawing on a rich array of sources, this article interprets this vice-charging as a rhetorical practice aimed at delineating empirical research from Naturphilosophie and Geschichtsphilosophie as practiced in the heyday of German Idealism. The strawman of “the philosopher” as invoked by historians and physicists served as a negative model for strongly empiricist scholars committed to virtues like precision, thoroughness, and conscientiousness. In their historical narratives, historians and physicists consistently depicted philosophy either as a relic from the past or as a phase that they had virtuously left behind. This boundary work was central to the self-positioning of both history and physics, which makes clear that the persona of the philosopher mattered not only to philosophers but also to scholars in adjacent disciplines.     

The False-Hope Syndrome: Unfulfilled Expectations of Self-Change

Why do people persist in attempting to change themselves, despite repeated failure? Self-change is often perceived as unrealistically easy to achieve, in an unreasonably short period of time. Moreover, embarking on self-change attempts induces feelings of control and optimism that supersede the lessons of prior experience. Finally, people tend to expect an unrealistically high payoff from successful self-change. Some sorts of self-change are feasible, but we must learn to distinguish between realistic and unrealistic self-change goals, between confidence and overconfidence. Overconfidence breeds false hope, which engenders inflated expectations of success and eventually the misery of defeat.     

The Janus face of power in intergroup contexts: a further exploration of the noblesse oblige effect

The authors examined the impact of power on in-group bias by manipulating group members' power over the in-group and power over the out-group as orthogonal factors. Each factor had 3 levels: 0%, 50%, and 100%. Participants were 216 male pupils (12-13 years old). Participants showed no in-group bias when they had 0% control over the in-group, strong in-group bias with 50% control, but less in-group bias with 100% control. Participants showed more in-group bias when they had 0% control over the out-group than when they had 50% or 100% control. The combination of these 2 main effects resulted in the noblesse oblige effect: Group members with complete control over both in-group and out-group expressed less in-group bias than did group members who shared control with an out-group.     

Agrammatic sentence production: is verb second impaired in Dutch?

This study investigates effects of verb movement in nine Dutch-speaking agrammatic aphasics. According to linguistic theory, in verb second languages such as Dutch and German, the verb remains in its clause-final base position in embedded clauses, whereas it moves to second position in main clauses. In recent linguistic accounts of agrammatic sentence production, it has been suggested that the production of sentences with moved verbs is relatively difficult. However, we argue that evidence provided by previous studies on this matter is inconclusive. An experiment is reported in which the production of both types of clauses is compared. No evidence is found that sentences with moved verbs are relatively difficult to produce. In fact, there was a tendency for the base order sentences to be harder. Implications of these findings for theories of normal and agrammatic sentence production are discussed.     

Exercise therapy for depression in middle-aged and older adults: predictors of early dropout and treatment failure.

Psychosocial factors predicting treatment dropout or failure to benefit from treatment were identified in a randomized trial of exercise therapy and pharmacotherapy for major depression. One hundred fifty-six men and women over age 50 diagnosed with major depressive disorder were assigned to a 16-week program of aerobic exercise, medication (sertraline), or a combination of exercise and medication. Thirty-two patients (21%) failed to complete the program and were considered treatment "dropouts." At the end of 16 weeks, 83 patients (53%) were in remission; the remaining patients not in remission were considered treatment "failures." Baseline levels of self-reported anxiety and lift satisfaction were the best predictors of both patient dropout and treatment success or failure across all treatment conditions.
