Self‐Control of Smoking: When Does Narrowed Attention Help?1

Two studies examined the capacity of cognitive load to enhance or disrupt the self‐control of smoking in the presence of situational pressures that either promote or discourage the behavior. In Study 1, participants who were exposed to cues encouraging smoking smoked more under high cognitive load than under low cognitive load. In Study 2, participants who were exposed to cues discouraging smoking smoked less under high load than under low load. Cognitive load appears to narrow attention, resulting in a state of attentional myopia, which leads to disinhibited smoking behavior when pressures to smoke are disproportionately salient and enhanced control of smoking when pressures not to smoke are disproportionately salient. Implications for smoking cessation are discussed.     

See no lies,hear no lies: differences in discrimination accuracy and response bias when watching or listening to police suspect interviews

In the present experiment, police officers attempted to detect truths and lies told by suspects in their police interviews in three different ways: They either saw the suspects (visual condition), only heard the suspects (audio condition) or both saw and heard the suspects (control condition). Research has demonstrated that vocal and speech‐related cues are better diagnostic cues to deceit than visual cues. Therefore, we predicted that participants in the visual condition would perform worst in the lie detection task. Having access only to visual cues may encourage observers to be more reliant on stereotypical beliefs when attempting to detect truths and lies. Since these stereotypes are related to the behaviour of liars, rather than to the behaviour of truth tellers, we further predicted that being exposed only to visual cues may result in a lie bias. The findings supported these hypotheses, and the implications are discussed. Copyright © 2007 John Wiley & Sons, Ltd.     

Reasons for Living versus Reasons for Dying: Examining the Internal Debate of Suicide

The Reasons for Living vs. Reasons for Dying (RFL/RFD) Assessment was used to obtain suicidal outpatients' top five reasons for living and for dying, respectively. Forty-nine suicidal university counseling center patients provided 173 RFL and 145 RFD responses. These responses were organized into eight RFL coding categories and nine RFD coding categories. Two coders trained in the RFL/RFD coding system showed high levels of inter-rater reliability (K_RFL = .81; K_RFD = .80). Chi-square results for RFL and RFD coding categories showed that the coding categories were not equally salient to these suicidal patients.     

Use of vocalic cues to consonant voicing and native language background: The influence of experimental design

For native speakers of English and several other languages, preceding vocalic duration andFi offset frequency are two of the cues that convey the stop consonant voicing distinction in wordfinal position. For speakers learning English as a second language, there are indications that use of vocalic duration, but notFl offset frequency, may be hindered by a lack of experience with phonemic (i.e., lexical) vowel length (the “phonemic vowel length account”: Crowther & Mann, 1992). In this study, native speakers of Arabic, a language that includes a phonemic vowel length distinction, were tested for their use of vocalic duration andF1 offset in production and perception of the English consonant-vowel-consonant forms pod and pot. The phonemic vowel length hypothesis predicts that Arabic speakers should use vocalic duration extensively in production and perception. On the contrary, experiment l repealed that, consistent with Flege and Port’s (1981) findings, they produced only slightly (but significantly) longer vocalic segments in their pod tokens. It further indicated that their productions showed a significant variation inFl offset as a function of final stop voicing. Perceptual sensitivity to vocalic duration andFl offset as voicing cues was tested in two experiments. In experiment 2, we employed a factorial combination of these two cues and a finely spaced vocalic duration continuum. Arabic speakers did not appear to be very sensitive to vocalic duration, but they were abort as sensitive as native English speakers toF1 offset frequency. In Experiment 3, we employed a one-dimensional continuum of more widely spaced stimuli that varied only vocalic duration. Arabic speakers showed native-English-like sensitivity to vocalic duration- Anexplanation based on tie perceptual anchor theory of context coding (Braida et al., 1984; Macmillan, 1987; Macmillan, Braida, & Goldberg, 1987) and phoneme perception theory (Schouten & Van Hessen, 2992) is offered to reconcile the apparently contradictory perceptual findings. The explanation does not attribute native-English-like voicing perception to the Ambit subjects. The findings in this study call fox a modification of the phonemic vowel length hypothesis.

Some philosophical directions towards a simple theory of the self

In the act of self-observation, an individual becomes simultaneously observer and observed, subject and object. While some philosophical psychologists have dismissed thisreflexivity, the present author proposes that it isthe essential feature of the self, making it the basis of a new, conceptually simple, structural and dynamic theory of the self. Drawing from psychopathology, poetry and literature, the author portrays normal and disordered psychological states as disturbances in reflexivity. Qualitative and quantitative variations in this core function are proposed to define discreet spectra of psychological situations. The author briefly examines the theories and practices of psychoanalytic and existential psychology, and proposes clinical applications of the new views here depicted. He attempts to show that inherent limits to our simultaneous knowledge of both aspects of the reflexive duality limit the precision and validity of all psychological theorization.     

Early Election Returns and the Voting Behavior of Adolescent Voters1

High school students participated in a field experiment that tested the effects of exposure to early election returns in a nonpartisan referendum. On a pretest of attitudes, students stated their preferences on the issue of the school's grading policy. One week later, just before voting, subjects in the experimental condition received information announcing the probable outcome of the election. There was a significant relationship between class achievement level and (a) likelihood of changing vote, and (b) the direction of change. Students in the brighter classes changed their votes less frequently, but when they changed their preferences they showed a greater bandwagon effect. Students in the classes of lower academic achievement changed their votes more frequently, but when they changed their preferences they showed a greater underdog effect. Differences between the more typical political election in which bandwagon and underdog effects are seldom reported and the experimental election were discussed.
