ARE ALL LATINAS THE SAME? PERCEIVED BREAST CANCER SCREENING BARRIERS AND FACILITATIVE CONDITIONS

In this article, we examine perceived breast cancer screening barriers and facilitative conditions for immigrant women from Mexico, Puerto Rico, Cuba, El Salvador, and South America ( N = 58). Focus groups conducted separately with women of each ancestry were analyzed using grounded theory methods. Identified barriers comprise secrecy, lack of information, embarrassment, fear, and distrust of health care providers. Perceived facilitative conditions include knowing the importance of early detection and noticing a symptom. We compare and contrast findings across ancestries and discuss how psychosocial and cultural factors could be better integrated into early detection programs. The women's high screening rates also suggest that breast cancer screening can be facilitated in this population by addressing institutional factors (e.g., access to health care, transportation).     

Testing discrepancy effects: A critique, a suggestion, and an illustration

To assess the effects of discrepancy between two independent variables, investigators sometimes compute difference scores and correlate such scores with a criterion variable. However, the correlation of the difference with the criterion is accounted for by the correlations of the difference constituents with the criterion and the constituents’ variances. It follows that when investigators are testing a prediction that is not captured by the difference constituents’ main effects, using the difference correlation analysis may be misleading. Under these circumstances, the effects of a discrepancy between two independent variables can be assessed by a test of their interaction. The problems inherent in using difference scores and the advantage of testing the interaction are illustrated in relation to research programs on two separate topics in social psychology.     

Connectionist semantic systematicity

Fodor and Pylyshyn [Fodor, J. A., & Pylyshyn, Z. W. (1988). Connectionism and cognitive architecture: A critical analysis. Cognition, 28, 3–71] argue that connectionist models are not able to display systematicity other than by implementing a classical symbol system. This claim entails that connectionism cannot compete with the classical approach as an alternative architectural framework for human cognition. We present a connectionist model of sentence comprehension that does not implement a symbol system yet behaves systematically. It consists in a recurrent neural network that maps sentences describing situations in a microworld, onto representations of these situations. After being trained on particular sentence–situation pairs, the model can comprehend new sentences, even if these describe new situations. We argue that this systematicity arises robustly and in a psychologically plausible manner because it depends on structure inherent in the world.     

Unveiling phonological universals: A linguist who asks "why" is (inter alia) an experimental psychologist

Evans and Levinson are right to hold theories of language accountable for language diversity, but typological data alone cannot determine the structure of mental phonological grammars. Grammatical universals are nonetheless testable by formal and experimental methods, and the growing research in experimental phonology demonstrates the viability of a comparative experimental evaluation of the UG hypothesis.     

Individuals high in neuroticism are not more reactive to adverse events

Numerous studies have related neuroticism to negative emotional outcomes of adverse life events, including post-traumatic stress disorder (PTSD) symptoms. However, the nature of the relationship between neuroticism and post-trauma symptoms is unclear. The purpose of this study was to prospectively examine whether individuals high in neuroticism, relative to low neuroticism individuals, show a larger increase in symptoms after an adverse event. A sample of infantry troops completed questionnaires before deployment to Iraq (n = 214) and about five months (n = 170; 76%) thereafter. The findings showed that, after controlling for an indicator of trauma severity, (a) higher neuroticism individuals reported more PTSD symptoms, depression symptoms, and somatic problems after negative events, and (b) these relationships disappeared after controlling for pre-trauma symptoms. There were no significant differences between individuals high and low in neuroticism in the increase in symptoms from pre to post-trauma. This suggests that individuals high in neuroticism are not more reactive to adverse events.     

The diagnosis and cure of garden paths

We propose that, for the human parser, recovery from garden paths consists in repairing the structure built so far, rather than reparsing the input. The difficulty of a repair is attributable not to the cost of effecting the structural alterations but to the cost of deducing which alterations are needed. The parser must diagnose its error in order to correct it. The error is signaled by an input word that is incompatible with the current structure; this is the symptom from which the diagnosis must be made. If the error is transparently clear from the nature of the symptom, recovery is easy; but sometimes the necessary reasoning is obscure, and then the diagnosis is unsuccessful and the garden path persists. Unlike other repair models, the diagnosis model needs no special mechanism for revising garden path analyses. The garden path recovery device is the same machine as the first-pass parser, merely set into emergency mode. When faced with a breakdown the parser does not stop its normal activities and enter a new mode of reasoning to detect what went wrong. It simply continues to parse, attaching the problematic input item in the least ungrammatical way it can, despite the conflict with previously built structure. This conflict is productive; it provokes adjustments to the existing structure. In successful cases, one adjustment leads to another until a stable state is reached, at which point the original error will have been eliminated. Examples suggest that the parser gives more weight to syntatctic than to pragmatic acceptability; only a syntactic clash between the input and the existing structure sets the adjustment process in motion.     

Concepts: a potboiler

An informal, but revisionist, discussion of the role that the concept of a concept plays in recent theories of the cognitive mind. It is argued that the practically universal assumption that concepts are (at least partially) individuated by their roles in inferences is probably mistaken. A revival of conceptual atomism appears to be the indicated alternative.
