Mimics: A symbolic conflict/cooperation simulation program,with embedded protocol recording and automatic psychometric assessment

This paper describes an interactive software environment designed as a social interaction simulator with embedded comprehensive recording and flexible assessment facilities. Using schematized visual sketches similar to cross-cultural facial universals (Ekman, 1999), Mimics (Shmelyov & Aidman, 1997) employs a computer-game-like scenario that requires the subject to identify with anavatar and navigate it through a playing field inhabited byhosts who display a range of facial expressions. From these expressions (which are highly consequential), the player has to anticipate the hosts’ reactions to the avatar (which may vary from friendly to obstructing or aggressive) and choose between negotiating with a host (by altering the avatar’s facial expression), attacking it, or searching for an escape route. Comprehensive recording of player moves and interactions has enabled computation of several finegrained indices of interactive behavior, such as aggressive response styles, efficiency, and motivation in conflict/cooperation contexts. Initial validation data and potential applications of the method in the assessment of personality and social behavior are discussed.     

Intuition: A fundamental bridging construct in the behavioural sciences

The concept of intuition has, until recently, received scant scholarly attention within and beyond the psychological sciences, despite its potential to unify a number of lines of inquiry. Presently, the literature on intuition is conceptually underdeveloped and dispersed across a range of domains of application, from education, to management, to health. In this article, we clarify and distinguish intuition from related constructs, such as insight, and review a number of theoretical models that attempt to unify cognition and affect. Intuition's place within a broader conceptual framework that distinguishes between two fundamental types of human information processing is explored. We examine recent evidence from the field of social cognitive neuroscience that identifies the potential neural correlates of these separate systems and conclude by identifying a number of theoretical and methodological challenges associated with the valid and reliable assessment of intuition as a basis for future research in this burgeoning field of inquiry.     

Effects of Including a Graphic Warning Label in Advertisements for Reduced‐Exposure Products: Implications for Persuasion and Policy1

Considerable interest has focused on making warning labels on tobacco‐product packaging more effective in communicating risk to current and potential smokers. However, none of this work to date has involved the communication of risk information about reduced‐exposure products, or how a graphic warning label may function in advertisements. Reduced‐exposure products pose an interesting public health challenge in light of the fact that many advertisements for such products convey safety claims that may undermine the likelihood that potential consumers will process warnings about the products. The present study examines the influence of graphic warning labels on ratings of advertisements for 3 different types of tobacco products. Results showed that including a graphic picture lowered the appeal ratings for the product.     

Use of experienced retrieval ease in self and social judgments

People base judgments from memory on both the content of the information they retrieve and the ease they experience in retrieving it (Schwarz, N., Bless, H., Strack, F., Klumpp, G., Rittenauer-Schatka, H., & Simons, A. (1991). Ease of retrieval as information: another look at the availability heuristic. Journal of Personality and Social Psychology, 61, 195-202). Four studies demonstrate that people rely relatively more on the experienced ease of recall when making judgments about the self compared to judgments about others. This pattern was found for judgments of an “average” (Study 1a) or specific (Study 1b) other. Subjective retrieval ease was less informative when people were relatively less familiar with the specific other person. Providing an alternative explanation for the experienced difficulty of recall affected self, but not social, assessments (Study 2). In addition, the effect generalized to risk judgments about a state of the world; namely, the safety of one’s town (Study 3). A deeper appreciation of when and why people rely on different sources of accessible information when making judgments may help in understanding and reducing social conflict.     

Selective blockade of 5-HT2A receptors attenuates the increased temperature response in brown adipose tissue to restraint stress in rats

Previous studies have demonstrated that 5-HT2A receptors may be involved in the central control of thermoregulation and of the cardiovascular system. Our aim was to test whether these receptors mediate thermogenic and tachycardiac responses induced by acute psychological stress. Three groups of adult male Hooded Wistar rats were instrumented with: (i) a thermistor in the interscapular area (for recording brown adipose tissue temperature) and an ultrasound Doppler probe (to record tail blood flow); (ii) temperature dataloggers to record core body temperature; (iii) ECG electrodes. On the day of the experiment, rats were subjected to a 30-min restraint stress preceded by s.c. injection of either vehicle or SR-46349B (a serotonin 2A receptor antagonist) at doses of 0.01, 0.1 and 1.0 mg/kg. The restraint stress caused a rise in brown adipose tissue temperature (from, mean +/- s.e.m., 36.6 +/- 0.2 to 38.0 +/- 0.2 degrees C), transient cutaneous vasoconstriction (tail blood flow decreased from 12 +/- 2 to 5 +/- 1 cm/s), increase in heart rate (from 303 +/- 15 to 453 +/- 15 bpm at the peak, then reduced to 393 +/- 12 bpm at the steady state), and defaecation (6 +/- 1 pellets per restraint session). The core body temperature was not affected by the restraint. Blockade of 5-HT2A receptors attenuated the increase in brown adipose tissue temperature and transient cutaneous vasoconstriction, but not tachycardia and defaecation elicited by restraint stress. These results indicate that psychological stress causes activation of 5-HT2A receptors in neural pathways that control thermogenesis in the brown adipose tissue and facilitate cutaneous vasoconstriction.     

Biases in the subjective timing of perceptual events: Libet et al. (1983) revisited

We report two experiments in which participants had to judge the time of occurrence of a stimulus relative to a clock. The experiments were based on the control condition used by Libet, Gleason, Wright, and Pearl [Libet, B., Gleason, C. A., Wright, E. W., & Pearl, D. K. (1983). Time of conscious intention to act in relation to onset of cerebral activities (readiness-potential): The unconscious initiation of a freely voluntary act. Brain 106, 623-642] to correct for any bias in the estimation of the time at which an endogenous event, the conscious intention to perform a movement, occurred. Participants' responses were affected systematically by the sensory modality of the stimulus and by the speed of the clock. Such findings demonstrate the variability in judging the time at which an exogenous event occurs and, by extension, suggest that such variability may also apply to the judging the time of occurrence of endogenous events. The reliability of participants' estimations of when they formed the conscious intention to perform a movement in Libet et al.'s (1983) study is therefore questionable.     

Empirical and theoretical limits on lag recency in free recall

One widely accepted empirical regularity in free recall holds that when people successively transition from report of one list item to another, they prefer transitions across short lags (e.g., by reporting items from adjacent serial positions) to transitions involving large lags. This regularity has provided crucial support for the temporal context model (TCM), a model of the evolution of temporal context in episodic memory (Howard & Kahana, 2002a). We report a reanalysis of 14 data sets that shows that, contrary to the presumed preference for short lags, people often produce transitions with larger lags during recall. We show that these data cannot be accommodated by the TCM. We furthermore show that existing applications of the model have, for mathematical convenience, introduced assumptions that have circumvented its core principle of context evolution. When we instantiated the TCM as it was actually described, with a gradually evolving context, we found that its behavior qualitatively departed from that of the version currently implemented, but that the model was still unable to capture the nature of transitions in free recall. We conclude that the TCM requires further modification and development before it can explain the data that constitute its main source of support.

Reflective practice framework for TESOL teachers: one teacher’s reflective journey

Just as in the field of general education, scholars within the field of teaching English to speakers of other languages (TESOL) have also struggled to come to a consensus as to how reflective practice should be operationalized with many different approaches suggesting a retrospective approach to questioning about practice. As a result, many of these approaches have led to a type of routinization of reflection. Worried about such routinization of reflection, Farrell developed a more holistic approach to reflective practice that recognizes the spiritual, moral, and emotional aspects of reflection, as well as the usual retrospective questions about practice. This paper outlines a case study of the reflections of one experienced TESOL teacher teaching in South Korea using Farrell’s framework for reflecting on practice that included reflections on his philosophy, principles, theory, practice, and beyond practice. The results revealed three common themes of approachability, art-oriented conceptions, and curiosity that emerged in all aspects of his reflection as uniquely influential parts of a larger whole. Thus, Farrell’s holistic framework for teacher reflection employed in this study provided multiple filters through which these various parts could be viewed.
