Introduction to the special section on aging, cognition, and neuroimaging

In response to the recent increase in the number of laboratories engaged in the use of functional and structural neuroimaging to study cognitive aging, this special section has been compiled to serve as an entry into this area for the readers of Psychology and Aging. These articles are representative of the field and cover many of the issues faced by researchers in this area. This introduction presents some background into the techniques that are used and provides an overview of the articles.     

Preference for spatial cues in a non-storing songbird species

Male mammals typically outperform their conspecific females on spatial tasks. A sex difference in cues used to solve the task could underlie this performance difference as spatial ability is reliant on appropriate cue use. Although comparative studies of memory in food-storing and non-storing birds have examined species differences in cue preference, few studies have investigated differences in cue use within a species. In this study, we used a one-trial associative food-finding task to test for sex differences in cue use in the great tit, Parus major. Birds were trained to locate a food reward hidden in a well covered by a coloured cloth. To determine whether the colour of the cloth or the location of the well was learned during training, the birds were presented with three wells in the test phase: one in the original location, but covered by a cloth of a novel colour, a second in a new location covered with the original cloth and a third in a new location covered by a differently coloured cloth. Both sexes preferentially visited the well in the training location rather than either alternative. As great tits prefer colour cues over spatial cues in one-trial associative conditioning tasks, cue preference appears to be related to the task type rather than being species dependent.     

Selection-based virtual keyboard prototypes and data collection application

An emerging area of research in engineering psychology is the evaluation of text entry for mobile devices using a small number of keys for the control of cursor direction and character selection from a matrix of characters (i.e., selection-based data entry). The present article describes a software tool designed to reduce time and effort in the development of prototypes of alternative selection-based text-entry schemes and their empirical evaluation. The tool, available for distribution to researchers, educators, and students, uses Action Script code compiled into an executable file that has an embedded Adobe Flash Player and is compatible with most operating systems (including Microsoft Windows, Apple OSX, and Linux).     

"Transitional objects" as establishing operations for thumb sucking: a case study

This study examines the effects of a "transitional object" (surgical cloth) on the thumb sucking of a 3-year-old boy in two conditions: while sitting in the lap of his physical therapist and while alone in his crib. Sucking occurred when the cloth was present and did not occur when it was absent, regardless of condition. These results are discussed in terms of establishing operations, object attachment, and application.     

Sharing as Hope and Celebration

And no one puts a piece of unshrunk cloth on an old garment, for the patch tears away from the garment and a worse tear is made. Neither is new wine put into old wineskins; if it is, the skins burst, and the wine is spilled, and the skins are destroyed; but new wine is put into fresh wineskins and so both are preserved. (Matt. 9:16–17)     

Mental health and welfare transitions: depression and alcohol abuse in AFDC women

From a selection perspective, does prior dysfunction select women into welfare or serve as a barrier to leaving welfare? From a social causation perspective, does entering or exiting welfare lead to changes in well being? These questions were analyzed in panel data for over 3,600 women drawn from the National Longitudinal Survey of Youth for the period 1992–94. Welfare is associated with both depression and alcohol consumption cross‐sectionally. This link appears to derive in small part from selection into welfare by depression (in interaction with marital status), but depression and alcohol abuse did not operate as barriers to leaving welfare. Entering welfare was clearly associated with increased depression and alcohol consumption, but confidence in an apparent beneficial effect on alcohol symptoms of leaving welfare for employment was limited by small sample sizes. These findings are located in the context of the 1996‐welfare reform and the recent economic expansion. One implication is that community psychology should consider welfare entry as a risk factor similar to adverse employment changes such as job loss.

Ownership as a social status

The authors suggest that ownership may be one of the critical entry points into thinking about social constructions, a kind of laboratory for understanding status. They discuss the features of ownership that make it an interesting case to study developmentally. In particular, ownership is a consequential social fact that is alterable by an individual, even a child. Children experience changes in ownership in a way they do not experience changes in other social facts (such as word meanings or social norms). Ownership is also an individual rather than a general property; two objects can be identical, but differ in ownership.     

Synaptic plasticity in the lateral amygdala: a cellular hypothesis of fear conditioning

Fear conditioning is a form of associative learning in which subjects come to express defense responses to a neutral conditioned stimulus (CS) that is paired with an aversive unconditioned stimulus (US). Considerable evidence suggests that critical neural changes mediating the CS-US association occur in the lateral nucleus of the amygdala (LA). Further, recent studies show that associative long-term potentiation (LTP) occurs in pathways that transmit the CS to LA, and that drugs that interfere with this LTP also disrupt behavioral fear conditioning when infused into the LA, suggesting that associative LTP in LA might be a mechanism for storing memories of the CS-US association. Here, we develop a detailed cellular hypothesis to explain how neural responses to the CS and US in LA could induce LTP-like changes that store memories during fear conditioning. Specifically, we propose that the CS evokes EPSPs at sensory input synapses onto LA pyramidal neurons, and that the US strongly depolarizes these same LA neurons. This depolarization, in turn, causes calcium influx through NMDA receptors (NMDARs) and also causes the LA neuron to fire action potentials. The action potentials then back-propagate into the dendrites, where they collide with CS-evoked EPSPs, resulting in calcium entry through voltage-gated calcium channels (VGCCs). Although calcium entry through NMDARs is sufficient to induce synaptic changes that support short-term fear memory, calcium entry through both NMDARs and VGCCs is required to initiate the molecular processes that consolidate synaptic changes into a long-term memory.

On Philosophical Translator-Advocates and Linguistic Injustice

Abstract

This paper argues for the need of philosophical translator-advocates to overcome the (would-be) limitations produced by the linguistic narrowness of analytic philosophy. It draws on a model used to analyze epistemic communities in order to characterize a form of linguistic injustice. In particular it does so by treating language as an epistemic barrier to entry of ideas and people and by treating philosophical translator-advocates as engaged in a form of arbitrage. Along the way I specify some necessary and jointly sufficient characteristics of a philosophical translator-advocate. My argument is illuminated and vivified with examples from the history of analytic philosophy and other episodes from the history of philosophy.     

A cognitive learning perspective on women becoming expert managers

Despite recent gains, women still face the glass ceiling—an invisible barrier that blocks their entry into top executive positions. Explanations for women's lack of success range from blaming men for discrimination to blaming women themselves. Rather than blaming the people in organizations, it is useful to analyze the task facing women managers. I argue that understanding the inherent difficulties in women's work can provide a new perspective on why women have difficulty in achieving top positions. Recent work in cognitive psychology is helping us learn more about the processes involved in reaching high levels of performance. Using these theories and concepts to analyze the task facing women managers, we can begin to develop new ways to help women develop higher levels of managerial skill.     

Alcohol expectancy multiaxial assessment: a memory network-based approach

Despite several decades of activity, alcohol expectancy research has yet to merge measurement approaches with developing memory theory. This article offers an expectancy assessment approach built on a conceptualization of expectancy as an information processing network. The authors began with multidimensional scaling models of expectancy space, which served as heuristics to suggest confirmatory factor analytic dimensional models for entry into covariance structure predictive models. It is argued that this approach permits a relatively thorough assessment of the broad range of potential expectancy dimensions in a format that is very flexible in terms of instrument length and specificity versus breadth of focus.     

Occupational perceptions of males and females as a function of sex ratios,salary, and availability

Undergraduate students' willingness to explore, enter, and predict success for themselves in three occupations was examined as a function of subject sex and information about occupational sex ratio, salary, and position availability. Factors considered by the 490 subjects in their decisions about exploration and entry likelihoods were also investigated. A multivariate design was used and results indicated males were more likely to report an interest in further exploration of and entry into the occupations, as well as to predict success for themselves. Males also placed more importance on the factor of salary in their decisions. The sexes differed somewhat in their overall rankings of the importance of various factors in their decisions. Results are discussed in terms of previous research literature and theory.     

Perceptual Sensitivity and Motoric Competence in 5- and 6-Month-Old Infants

The authors explored whether 5- to 6-month-old infants were sensitive to perceptual information and how they used perception as a recognition cue to search for a hidden object. In addition, the authors categorized and examined infant grasp by developmental effectiveness to determine any impact on infant search behaviors. In a within-participants design, 20 infants were presented with a toy in 2 occluder conditions. The toy was hidden under either a thick, camouflaging cloth or a thin, semitransparent cloth. The data revealed significant effects of perceptual sensitivity, age, and motor sophistication on search tasks. The results suggest that motor competence might be a limiting factor in infants' abilities to link motoric responses to notions about an object.     

Helper plus trainer: a two-phase program for the counselor

Helping is what it's all about. But if we recognize that one way to help is to train someone else to do a part of what we can do, we can assist that many more people with our limited resources. Thus, to be professionally adequate through all dimensions of the Cube requires the capacity to “train” as well as to “help.” Delworth and Moore have had extensive experience in both modes and have trained literally hundreds of paraprofessionals on a wide range of tasks. Their expertness shows through particularly in their recognition that training is not complete until the trainee has mastered the barrier of systems entry. Too many well-meaning and adequately skilled counselors have had their noses flattened because they did not have the “key” to the system. Too many well-meaning and adequately skilled counselors have remained in their offices because they lacked the ability to “multiply” their efforts through others. Here is a schematic to facilitate change in both kinds of counselors.     

The onset of dementia caregiving and its longitudinal implications

This study examined patterns of entry into the caregiving role and how onset influences outcomes pertinent to the caregiving process. Using 3-year longitudinal data, the present analysis classified dementia caregivers into 1 of 4 onset sequences: those whose entry into caregiving was defined by diagnosis, those who first recognized symptoms and then obtained a diagnosis, those caregivers who first recognized symptoms and then provided care, and those who provided care prior to diagnosis or recognition. Analyses revealed that respondents who experienced a less abrupt entry into caregiving were less likely to institutionalize their relatives and reported greater decreases in well-being. The findings point to the dynamic process that defines entry into caregiving and emphasize that how individuals assume caregiving roles have implications long after onset.     

Conditioned reinforcement by conditional discriminative stimuli.

A concurrent-chains schedule was used to examine how a delay to conditional discriminative stimuli affects conditioned reinforcement strength. Pigeons' key-peck responses in the initial link produced either of two terminal links according to independent variable-interval 30-s schedules. Each terminal link involved an identical successive conditional discrimination and was segmented into three links: a delay interval (green), a color conditional discriminative stimulus (blue or red), and a line conditional discriminative stimulus (vertical or horizontal lines). Food delivery occurred 45 s after entering the terminal link with a probability of .5, but its conditional probability (1.0 or 0) depended on the combination of the color and the line stimuli. One of the color stimuli occurred independently of further responding, 5 s after entry into the right terminal link, but it occurred 35 s after entry into the left terminal link. One of the line stimuli occurred independently of responding 40 s after entry into either terminal link, synchronized with the offset of the color stimulus. The initial-link relative response rate for the right was consistently higher in comparison with a control condition in which the color stimuli occurred 20 s after entry into either terminal link. The preference for the short delay to the color conditional discriminative stimuli suggests the possibility of conditioned reinforcement by information about the relation between the line conditional discriminative stimuli and the outcomes.
