The evolution of the language faculty: clarifications and implications

In this response to Pinker and Jackendoff's critique, we extend our previous framework for discussion of language evolution, clarifying certain distinctions and elaborating on a number of points. In the first half of the paper, we reiterate that profitable research into the biology and evolution of language requires fractionation of "language" into component mechanisms and interfaces, a non-trivial endeavor whose results are unlikely to map onto traditional disciplinary boundaries. Our terminological distinction between FLN and FLB is intended to help clarify misunderstandings and aid interdisciplinary rapprochement. By blurring this distinction, Pinker and Jackendoff mischaracterize our hypothesis 3 which concerns only FLN, not "language" as a whole. Many of their arguments and examples are thus irrelevant to this hypothesis. Their critique of the minimalist program is for the most part equally irrelevant, because very few of the arguments in our original paper were tied to this program; in an online appendix we detail the deep inaccuracies in their characterization of this program. Concerning evolution, we believe that Pinker and Jackendoff's emphasis on the past adaptive history of the language faculty is misplaced. Such questions are unlikely to be resolved empirically due to a lack of relevant data, and invite speculation rather than research. Preoccupation with the issue has retarded progress in the field by diverting research away from empirical questions, many of which can be addressed with comparative data. Moreover, offering an adaptive hypothesis as an alternative to our hypothesis concerning mechanisms is a logical error, as questions of function are independent of those concerning mechanism. The second half of our paper consists of a detailed response to the specific data discussed by Pinker and Jackendoff. Although many of their examples are irrelevant to our original paper and arguments, we find several areas of substantive disagreement that could be resolved by future empirical research. We conclude that progress in understanding the evolution of language will require much more empirical research, grounded in modern comparative biology, more interdisciplinary collaboration, and much less of the adaptive storytelling and phylogenetic speculation that has traditionally characterized the field.     

Showing and telling about emotions: Interrelations between facets of emotional competence and associations with classroom adjustment in Head Start preschoolers

In this study of low income preschoolers (N?=? 60), we examined relations between three facets of emotional competence: emotion knowledge, level of negative emotion expression, and emotion regulation; and their associations with indicators of classroom adjustment. Emotion knowledge was positively related to positive emotion regulation but was not related to negative emotion expression or negative dysregulation. Negative emotion expression related to emotion regulation variables in expected directions. Negative emotion expression was associated with aggression and social skills after covarying verbal ability, age, and emotion knowledge. Negative dysregulation was related in expected directions to aggression, anxiety, and social skills after covarying verbal ability, age, emotion knowledge, and negative emotion expression. Positive emotion regulation was related negatively to anxiety and positively to social skills after covarying all other variables in the model. Results are discussed with regard to using the emotional competence domain to understand how emotion processing relates to early childhood adjustment.     

Behavioral Problems and Reading Difficulties Among Language Minority and Monolingual Urban Elementary School Students

This study examined the potentially compounding effect of language minority (LM) status on problem behaviors among urban second and third grade-level poor readers. Univariate analyses showed that a disproportionate percentage of both LM and English monolingual (L1) poor readers already displayed clinically significant levels of anxiety, social problems, and oppositional behaviors in the classroom. Analyses of variance, however, demonstrated that LM status was not an additive risk factor for reading difficulties, behavior problems, or lowered self-concept in this sample. No differences were observed between LM and L1 students on a wide range of reading measures, on their teachers’ ratings of internalizing and externalizing problem behaviors in the classroom, or on self-ratings of self-efficacy and social competence. Implications for intervention for all urban students with reading difficulties are discussed.     

Review: Being israeli

A disproportionate number of American Jewish and Israeli-born public intellectuals, including theorists such as Michael Walzer and Yael Tamir, have played a significant role in mapping the parameters of what it means to be a citizen and part of a particular ethnic or national group today. Many of these theorists share an interest in challenging the dominant nationalist outlook by articulating the moral and practical case for minority ethnic, national, and religious groups. While scholars of Jewish studies have long left public intellectuals who happen to be Jewish outside the parameters of the field, this study suggests expanding Jewish political thought to consider the connection between Jewish interests and mainstream theories of nationalism and multiculturalism.     

Psychoacoustic abilities as predictors of vocal emotion recognition

Prosodic attributes of speech, such as intonation, influence our ability to recognize, comprehend, and produce affect, as well as semantic and pragmatic meaning, in vocal utterances. The present study examines associations between auditory perceptual abilities and the perception of prosody, both pragmatic and affective. This association has not been previously examined. Ninety-seven participants (49 female and 48 male participants) with normal hearing thresholds took part in two experiments, involving both prosody recognition and psychoacoustic tasks. The prosody recognition tasks included a vocal emotion recognition task and a focus perception task requiring recognition of an accented word in a spoken sentence. The psychoacoustic tasks included a task requiring pitch discrimination and three tasks also requiring pitch direction (i.e., high/low, rising/falling, changing/steady pitch). Results demonstrate that psychoacoustic thresholds can predict 31% and 38% of affective and pragmatic prosody recognition scores, respectively. Psychoacoustic tasks requiring pitch direction recognition were the only significant predictors of prosody recognition scores. These findings contribute to a better understanding of the mechanisms underlying prosody recognition and may have an impact on the assessment and rehabilitation of individuals suffering from deficient prosodic perception.     

Targeting Self-Stigma in Returning Military Personnel and Veterans: A Review of Intervention Strategies

Research suggests that mental health-related stigma significantly decreases the use of mental health services by military personnel and veterans. The goal of this article is to review what is known about mental health stigma as it relates to military personnel and veterans, as well as to offer an interpretive review of self-stigma intervention strategies that have been applied within the field. Target areas for future work and the concerns and challenges faced by interventionists are discussed.     

Depth perception: cuttlefish (Sepia officinalis) respond to visual texture density gradients

Studies concerning the perceptual processes of animals are not only interesting, but are fundamental to the understanding of other developments in information processing among non-humans. Carefully used visual illusions have been proven to be an informative tool for understanding visual perception. In this behavioral study, we demonstrate that cuttlefish are responsive to visual cues involving texture gradients. Specifically, 12 out of 14 animals avoided swimming over a solid surface with a gradient picture that to humans resembles an illusionary crevasse, while only 5 out of 14 avoided a non-illusionary texture. Since texture gradients are well-known cues for depth perception in vertebrates, we suggest that these cephalopods were responding to the depth illusion created by the texture density gradient. Density gradients and relative densities are key features in distance perception in vertebrates. Our results suggest that they are fundamental features of vision in general, appearing also in cephalopods.
