The cost of serially chaining two cognitive operations

As Turing (1936, Proceedings of the London Mathematical Society) noted, a fundamental process in human cognition is to effect chained sequential operations in which the second operation requires an input from the preceding one. Although a great deal is known about the costs associated with 'independent' (unrelated) operations, e.g., from the classic psychological refractory period paradigm, far less is known about those operations to which Turing referred. We present the results of two behavioural experiments, where participants were required to perform two speeded sequential tasks that were either chained or independent. Both experiments reveal the reaction time cost of chaining, over and above classical dual-task serial costs. Moreover, the chaining operation significantly altered the distribution of reaction times relative to the Independent condition in terms of an increased mean and variance. These results are discussed in terms of the cognitive architecture underlying the serial chaining of cognitive operations.     

The Role of Regulatory Focus in the Experience and Self‐Control of Desire for Temptations

This research examines the role of regulatory focus in the experience and control of desire for temptations, the fulfillment of which conflicts with other salient goals of the consumer. Relative to a prevention focus (i.e., an orientation away from negative outcomes), our findings demonstrate that a promotion focus (i.e., an orientation toward positive outcomes) not only increases the intensity of desire experienced on encountering a temptation, but also increases success of its subsequent resistance. Differences in self‐control efficacy are found to be mediated by the type of self‐control strategies consumers use in the 2 foci. Convergent evidence obtained in 4 studies, considering situational and dispositional aspects of regulatory focus, indicates that when temptations are encountered by consumers, regulatory focus is an important determinant of the degree of desire, and the nature and outcome of self‐control.     

Learning in a task of complex auditory streaming and identification

Adult humans were studied for improvements in their ability to segregate natural whole speech in background noise, in 6 test sessions spaced with a very wide range of inter-session interval (ISI) ranging from minutes to weeks apart so as to examine the effect of this parameter on initial (early) and late components of perceptual learning. Improvements were found even with spacings of 3 weeks between the punctate task sessions. All subjects showed similar total learning amounts but there were sex- and ISI-dependent differences in learning patterns, which we indexed by dividing the overall exponentially-decreasing learning pattern into an early phase between the first two sessions and a later phase between the second and sixth sessions. Males tested at all ISIs and females tested at short (2, 5 and 15 min) and long (1–21 days) ISIs showed small amounts of early-phase learning and large amounts of late-phase learning. However, females tested at intermediate (30 min and 1 h) ISIs showed only early learning, i.e., faster learning given that the total learning was the same. This sex- and ISI-specific deviant pattern could be changed to the standard pattern by interposing an overnight interruption that included sleep amongst test sessions. Thus, improvement in this complex auditory streaming and identification task can occur even with very brief and widely-spaced exposure, generally through a standard pattern of slower overall learning, but also through a sex- and ISI-specific deviant pattern of very rapid early learning which can be modulated by interposed delay unlike the standard pattern.     

The Abbreviated Math Anxiety Scale (AMAS): construction,validity, and reliability

Psychometric properties of mathematics anxiety measures have not adequately been studied. Using a large sample size (N = 1,239), the authors developed an abbreviated math anxiety measure, examined its psychometric properties, and assessed the generalizability of the model across samples. Exploratory factor analysis yielded a nine-item measure and strong internal consistency, test-retest reliability, and good convergent/divergent validity was demonstrated with an independent sample. When administered to a replication sample, indexes suggested an excellent model fit. TheAbbreviated Math Anxiety Scale (AMAS) may represent a more parsimonious and valid approach to assess mathematics anxiety.     

Cultural unconscious in research: integrating multicultural and depth paradigms in qualitative research

Culturally focused research has gained momentum in many disciplines, including psychology. However, much of this research fails to pay attention to the unconscious dynamics that underlie the study of culture and culturally influenced human beings. Such dynamics may be especially significant when issues of marginalization and oppression are present. Therefore, this paper seeks to contribute a framework for understanding cultural dynamics, especially unconscious cultural dynamics, within depth psychological qualitative research influenced by Jungian and post‐Jungian scholarship. Inquiry that is approached with a commitment to making the unconscious conscious seeks to empower and liberate not only the subject/object studied but also the researchers themselves. Following a brief review of multiculturalism in the context of analytically informed psychology, this paper offers several case examples that focus on researchers' integration of awareness of the cultural unconscious in their study of cultural beings and topics.     

The Contribution of Executive Function to Source Memory Development in Early Childhood

Age-related differences in episodic memory judgments assessing recall of fact information and the source of this information were examined. The role of executive function (EF) in supporting early episodic memory ability was also explored. Four- and 6-year-old children were taught 10 novel facts from two different sources (experimenter or puppet), and memory for both fact and source information was later tested. Measures of working memory, inhibitory control, and set shifting were obtained to produce an indicator of children's EF. Six-year-olds recalled more fact and source information than did 4-year-olds. Regression analyses revealed that age, language ability, and EF accounted for unique variance in children's fact recall and source recall performance. These findings suggest a link between episodic memory and EF, and we propose that developmental investigations should further explore this association.
