Subjectivity in parent-infant relationships: A discussion of internal working models

Bowlby (1969/1982, 1973, 1980) has proposed that internal working models of self and other are psychic structures that guide an individual's subjective experience of and responses to others in important relationships. They are termed “working” models because they are believed to be dynamic mental representations that are modifiable, although they are presumed to become more resistant to change after the early years. This paper reviews Bowlby's construct of internal working models, including some recent empirical evidence usefully explained by the construct. The authors apply the construct of working models to parents' subjective experiences of their infants and review some preliminary evidence that suggests that parental working models of their infants are present even prior to the infants' birth and influence the parents' perception and interpretation of the infants' characteristics and behaviors. The authors then consider the development of infants' working models of self and other in the context of parental attributions. They conclude that subjectivity in parent-infant relationships is an exciting and promising area for investigation, although, at present, future progress is limited by problems of measurement. A brief discussion of directions for future research is included.     

Memorization and recall of very long lists accounted for within the Long-Term Working Memory framework

In a recent paper, Hu, Ericsson, Yang, and Lu (2009) found that an ability to memorize very long lists of digits is not mediated by the same mechanisms as exceptional memory for rapidly presented lists, which has been the traditional focus of laboratory research. Chao Lu is the holder of the Guinness World Record for reciting the most decimal positions of pi, yet he lacks an exceptional memory span for digits. In the first part of this paper we analyzed the reliability and structure of his reported encodings for lists of 300 digits and his application of the story mnemonic. Next, his study and recall times for lists of digits were analyzed to test hypotheses about his detailed encoding processes, and cued-recall performance was used to assess the structure of his encodings. Three experiments were then designed to interfere with the uniqueness of Chao Lu's story encodings, and evidence was found for his remarkable ability to adapt his encoding processes to reduce the interference. Finally, we show how his skills for encoding and recalling long lists can be accounted for within the theoretical framework of Ericsson and Kintsch's (1995) Long-Term Working Memory.     

The role of intuition and deliberative thinking in experts' superior tactical decision-making

Current theories argue that human decision making is largely based on quick, automatic, and intuitive processes that are occasionally supplemented by slow controlled deliberation. Researchers, therefore, predominantly studied the heuristics of the automatic system in everyday decision making. Our study examines the role of slow deliberation for experts who exhibit superior decision-making outcomes in tactical chess problems with clear best moves. Our study uses advanced computer software to measure the objective value of actions preferred at the start versus the conclusion of decision making. It finds that both experts and less skilled individuals benefit significantly from extra deliberation regardless of whether the problem is easy or difficult. Our findings have important implications for the role of training for increasing decision making accuracy in many domains of expertise.     

Prevalence and effects of life event exposure among undergraduate and community college students

The purposes of this study were to assess lifetime and recent exposure to various life events among undergraduate and community college students and to assess the relation between event exposure and a broad range of outcomes (i.e., mental and physical health, life satisfaction, grade point average). Undergraduate students from a midwestern university (N = 842) and a community college (N = 242) completed online measures of lifetime event exposure and outcomes at Time 1 and recent event exposure at Time 2 two months later. Life events assessed included events that did and did not meet the definition of a traumatic event (i.e., posttraumatic stress disorder Criterion A1) in the Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.; DSM-IV-TR; American Psychiatric Association, 2000) as well as directly (e.g., own life-threatening illness) and indirectly (e.g., others' illness) experienced events. Students reported experiencing many lifetime and recent Criterion A1 and non-A1 events, and community college students reported more events than did university students. Generally, individuals who reported more lifetime events also reported poorer outcomes (e.g., poorer health). The number of non-Criterion A1 and directly experienced events tended to be more strongly correlated with negative outcomes than were the number of Criterion A1 and indirectly experienced events reported. These findings suggest that non-A1 events are important to assess and can be significantly related to outcomes for students.     

Cultural consensus theory for multiple consensus truths

Cultural Consensus Theory (CCT) is a popular information pooling methodology used in the social and behavioral sciences. CCT consists of cognitive models designed to determine a consensus truth shared by a group of informants (respondents), and to better understand the cognitive characteristics of the informants (e.g. level knowledge, response biases). However prior to this paper, no CCT models have been developed that allow the possibility of the informant responses to come from a mixture of two or more consensus answer patterns. The major advance in the current paper is to endow one of the popular CCT models, the General Condorcet Model (GCM) for dichotomous responses, with the possibility of having several latent consensus answer patterns, each corresponding to a different, latent subgroup of informants. In addition, we augment the model to allow the possibility of questions having differential difficulty (cultural saliency). This is the first CCT finite-mixture model, and it is named the Multi-Culture GCM (MC-GCM). The model is developed axiomatically and a notable property is derived that can suggest the appropriate number of mixtures for a given data set. The model is extended in a hierarchical Bayesian framework and its application is successfully demonstrated on both simulated and real data, including a new experimental data set on political viewpoints.     

Improved Regression Calibration

The likelihood for generalized linear models with covariate measurement error cannot in general be expressed in closed form, which makes maximum likelihood estimation taxing. A popular alternative is regression calibration which is computationally efficient at the cost of inconsistent estimation. We propose an improved regression calibration approach, a general pseudo maximum likelihood estimation method based on a conveniently decomposed form of the likelihood. It is both consistent and computationally efficient, and produces point estimates and estimated standard errors which are practically identical to those obtained by maximum likelihood. Simulations suggest that improved regression calibration, which is easy to implement in standard software, works well in a range of situations.     

Emotional responses in spider fear are closely related to picture awareness

Theories of emotion propose that responses to emotional pictures can occur independently of whether or not people are aware of the picture content. Because evidence from dissociation paradigms is inconclusive, we manipulated picture awareness gradually and studied whether emotional responses varied with degree of awareness. Spider fearful and non-fearful participants viewed pictures of spiders and flowers at four levels of backward masking while electrodermal activity and heart rate were measured continuously. Recognition ratings confirmed that participants' picture awareness decreased with masking. Critically, effects of spider fear on emotion ratings and heart rate also decreased with masking. These findings suggest that effects of spider fear on emotion ratings and heart rate are closely related to picture awareness.     

Filial Obligations: A Contextual, Pluralist Model

In this article I investigate the nature and extent of filial obligations. The question what (adult) children owe their parents is not only philosophically interesting, but also of increasing relevance in ageing societies. Its answer matters to elderly people and their adult children, and is relevant to social policy issues in various ways. I present the strongest arguments for and against three models of filial obligations: the ??past parental sacrifices?? model, the ??special relationship?? model, and the conventionalist model. There is something to be said??and after consideration of objections something remains to be said??for all three models. In other words: filial obligations have more than one source, and an adequate model of filial obligations should reflect this. On its own, each of the above models is one-sided. They also fail to show the connections between the question of filial obligations and various other issues, such as issues of gender justice, the extent of institutionalization of eldercare, and social conventions regarding filial responsibility. Therefore, I integrate what I think we should keep from the aforementioned models into a contextual, pluralist model, which places filial obligations in a broader social and cultural context and relates them to issues of social justice. The model also highlights the difference between general and specific filial obligations, and the factors that determine their nature and extent, thus enabling a deeper and more comprehensive understanding of filial obligations.     

Eliciting cues to deception and truth: What matters are the questions asked

In this paper we argue that there is little need for more of the traditional deception detection research in which observers assess short video clips in which there are few (if any) cues to deception and truth. We argue that a change in direction is needed and that researchers should focus on the questions the interviewer needs to ask in order to elicit and enhance cues to deception. We discuss three strands of research into this new ‘interviewing to detect deception’ approach. We encourage practitioners to use the proposed techniques and encourage other researchers to join us in conducting more research in this area. We offer some guidelines for what researchers need to keep in mind when carrying out research in this new paradigm.
