Sex differences in scanning faces: Does attention to the eyes explain female superiority in facial expression recognition?

Previous meta-analyses support a female advantage in decoding non-verbal emotion (Hall, 1978, 1984), yet the mechanisms underlying this advantage are not understood. The present study examined whether the female advantage is related to greater female attention to the eyes. Eye-tracking techniques were used to measure attention to the eyes in 19 males and 20 females during a facial expression recognition task. Women were faster and more accurate in their expression recognition compared with men, and women looked more at the eyes than men. Positive relationships were observed between dwell time and number of fixations to the eyes and both accuracy of facial expression recognition and speed of facial expression recognition. These results support the hypothesis that the female advantage in facial expression recognition is related to greater female attention to the eyes.     

Longitudinal Multi-Trait-State-Method Model Using Ordinal Data

Multi-trait multi-method (MTMM) models provide a way to assess convergent and discriminant validity when multiple traits are measured by multiple methods. In recent years, longitudinal extensions of MTMM models have been proposed in the structural equation modeling framework to evaluate whether and how the trait as well as method factors change over time. We propose a novel longitudinal ordinal MTMM model that can be used to effectively distinguish volatile “state” processes from “trait” processes that tend to remain stable and invariant over time. The proposed model, termed a longitudinal multi-trait-state-method (LM-TSM) model, combines 3 key modeling components: (a) a measurement model for ordinal data, (b) a vector autoregressive moving average model at the latent level to examine changes in the state as well as the method factors over time, and (c) a second-order factor-analytic model to capture time-invariant traits as shared variances among the state factors across all measurement occasions. Data from the Affective Dynamics and Individual Differences (ADID; Emotions and Dynamic Systems Laboratory, 2010 Emotions and Dynamic Systems Laboratory. (2010).

Methodological issues associated with fitting the LM-TSM model are discussed.     

The Effect of Strenuous and Exhaustive Exercise on Learning

In view of reported effects of strenuous and exhaustive exercise on CNS activity, it was hypothesized that “fatiguing” exercise may influence learning retroactively as predicted by consolidation theory. Prelimary findings from two animal experiments are reported followed by a discussion of implications for future research.     

Keeping an eye on the truth? Pupil size changes associated with recognition memory

During recognition memory tests participants' pupils dilate more when they view old items compared to novel items. We sought to replicate this "pupil old/new effect" and to determine its relationship to participants' responses. We compared changes in pupil size during recognition when participants were given standard recognition memory instructions, instructions to feign amnesia, and instructions to report all items as new. Participants' pupils dilated more to old items compared to new items under all three instruction conditions. This finding suggests that the increase in pupil size that occurs when participants encounter previously studied items is not under conscious control. Given that pupil size can be reliably and simply measured, the pupil old/new effect may have potential in clinical settings as a means for determining whether patients are feigning memory loss.     

Epistemic normativity in Kant's “Second Analogy”

In the “Second Analogy,” Kant argues that, unless mental contents involve the concept of causation, they cannot represent an objective temporal sequence. According to Kant, deploying the concept of causation renders a certain temporal ordering of representations necessary, thus enabling objective representational purport. One exegetical question that remains controversial is this: how, and in what sense, does deploying the concept of cause render a certain ordering of representations necessary? I argue that this necessitation is a matter of epistemic normativity: with certain causal presuppositions in place, the individual is obliged to make a judgment with certain temporal contents, on pain of irrationality. To make this normatively obligatory judgment, the subject must place her perceptual representations in a certain order. This interpretation fits Kant's text, his argumentative aims, and his broader views about causal inference, better than rival interpretations can. This result has important consequences for the ongoing debate over the role of normativity in Kant's philosophy of mind.     

Content in a Dynamic Context

The standing tradition in theorizing about meaning, since at least Frege (1882), identifies meaning with propositions, which are, or determine, the truth‐conditions of a sentence in a context. But a recent trend has advocated a departure from this tradition: in particular, it has been argued that modal claims do not express standard propositional contents. This non‐propositionalism has received different implementations in expressivist semantics (Moss, 2015; Swanson, 2006; Yalcin, 2007) and certain kinds of dynamic semantics (Gillies, 2004, 2010; von Fintel and Gillies, 2007; Veltman, 1985, 1996). They maintain that the key aspect of interpretation of modal claims is the characteristic dynamic effect they have on the context. I argue that pessimism about truth‐conditions arises from an overly simplistic picture of content, context and their interaction. While I agree with the critics that an important aspect of modal meaning is the dynamic effect modals have on the context, I argue that they have mischaracterized the nature and the complexity of this effect. A more nuanced account of the interaction between modals and context shows that far from being incompatible with propositional meaning, the dynamic aspect of meaning is precisely what allows us to predict the correct propositional content of an utterance.     

Psychometric evaluation of the Multidimensional Assessment of Fatigue scale for use with pregnant and postpartum women

Although fatigue is a common experience for pregnant women and new mothers, few measures of fatigue have been validated for use with this population. To address this gap, the authors assessed psychometric properties of the Multidimensional Assessment of Fatigue (MAF) scale, which was used in 2 independent samples of pregnant women. Results indicated that the psychometric properties of the scale were very similar across samples and time points. The scale possesses a high level of internal consistency, has good convergent validity with measures of sleep quality and depression, and discriminates well from a measure of social support. Contrary to previous evaluations of the MAF, data strongly suggest that the scale represents a unidimensional construct best represented by a single factor. Results indicate that the MAF is a useful measure of fatigue among pregnant and postpartum women.     

Validation and error in multiplicative utility functions

An approach to the concept of error in utility assessment is proposed. Four kinds of errors are considered and each kind is related to four separate elicitation methods - all in the context of a general multiplicative multiattribute utility model. The methods are a Keeney-Raiffa (1976) procedure; SMART, for Simple Multi-Attribute Rating Technique (Edwards 1977); SJT, for a Social Judgment Theory based regression model (Hammond et al. 1975); and HOPE, for Holistic Orthogonal Parameter Estimation (Barron and Person 1979).The individual judgments elicited are either holistic - in which the entity to be evaluated is considered as a whole - or decomposed - in which attention is directed to one or two aspects at a time.If a general multiplicative model can be assumed to be an appropriate representation of the decision maker's basic preference structure, error can occur in the direct estimation of the scaling constants and univariate utility functions for decomposition methods (Keeney-Raiffa and SMART), or in the holistic assessments for holistic methods (SJT and HOPE). Individual estimates may be merely subject to random noise or may be substantially incorrect. The utility model may be incorrectly specified; finally, all four methods may be subject to systematic error. The four assessment methods are considered in conjunction with errors of each kind.     

Selecting K of N alternatives

In some decision contexts (e.g. graduate admissions) the task to select a subset of k distinct alternatives from among the N > k > 1 options available. For moderate values of N and k, the number of possible subsets of size k becomes quite large. Assuming alternatives are evaluated using consistent, though not explicit weights, selecting k, rather than 1, empirically excludes a substantial proportion (more than 80%) of the subsets; unfortunately to the unaided decision maker it is not obvious which subsets should be excluded. The tendency of subjects to select excludable subsets can be called an ‘infeasibility’ bias. The experimental evidence surprisingly shows no ‘infeasibility’ bias, as subjects overwhelmingly chose non-excluded selections.     

Invasive partners: an exploration of attachment, communication and family patterns

Therapists'ratings on a sample of heterosexual couples receiving marital or partnership counselling were used to develop measures of'invasive'behaviour by the adults concerned. We suggest that this behaviour stems from difficulties in attachment and is marked by a desire to stay close to the other person, difficulties in communication, difficulties in handling relationships between three people, and problems associated with the birth of a baby. A particular feature of this behaviour is that one or other partner attempts to restrict communication from the other, perhaps in order to avoid surprises which are perceived as a threat to the relationship. Invasiveness by wives was high in those couples who had had problems after the birth of a baby and significantly lower in those who had not. Implications for practice are discussed.
