The low-frequency encoding disadvantage: Word frequency affects processing demands

Low-frequency words produce more hits and fewer false alarms than high-frequency words in a recognition task. The low-frequency hit rate advantage has sometimes been attributed to processes that operate during the recognition test (e.g., L. M. Reder et al., 2000). When tasks other than recognition, such as recall, cued recall, or associative recognition, are used, the effects seem to contradict a low-frequency advantage in memory. Four experiments are presented to support the claim that in addition to the advantage of low-frequency words at retrieval, there is a low-frequency disadvantage during encoding. That is, low-frequency words require more processing resources to be encoded episodically than high-frequency words. Under encoding conditions in which processing resources are limited, low-frequency words show a larger decrement in recognition than high-frequency words. Also, studying items (pictures and words of varying frequencies) along with low-frequency words reduces performance for those stimuli.     

Roles of instruments in psychological research

What roles have instruments played in psychology and related disciplines? How have instruments affected the dynamics of psychological research, with what possibilities and limits? What is the psychological instrument? This article provides a conceptual foundation for specific case studies concerning such questions. The discussion begins by challenging widely accepted assumptions about the subject and analyzing the general relations between scientific experimentation and the uses of instruments in psychology. Building on this analysis, a deliberately inclusive definition of what constitutes a psychological instrument is proposed. The discussion then takes up the relation between instrumentation and theories and differentiates in greater detail the roles instruments have had over the course of psychology's history. Finally, the authors offer an approach to evaluating the possibilities and limitations of instruments in psychology.     

The effects of word frequency and similarity on recognition judgments: the role of recollection

K. J. Malmberg, J. Holden, and R. M. Shiffrin (2004) reported more false alarms for low- than high-frequency words when the foils were similar to the targets. According to the source of activation confusion (SAC) model of memory, that pattern is based on recollection of an underspecified episodic trace rather than the error-prone familiarity process. The authors tested the SAC account by varying whether participants were warned about the nature of similar foils and whether the recognition test required the discrimination. More false alarms for low-frequency similar items occurred only when participants were not warned at study about the subtle features to be discriminated later. The differential false-alarm rate by word frequency corresponded to the pattern of remember responses obtained when the test instructions did not ask for a subtle discrimination, supporting the SAC account that reversed false-alarm rates to similar foils are based on the recollection process.     

Role of appearance and nonverbal behaviors in the perception of sexual orientation among lesbians and gay men

According to the zero-acquaintance paradigm gay men and lesbians possess the ability to identify other homosexuals accurately after only very brief interpersonal contact. Given the vulnerability gay men and lesbians face in terms of antigay violence and prejudice, perceptual accuracy provides self-protection. In an exploratory study, 123 respondents were classified as low, moderate, and high perceivers on the basis of their responses to a recognition index designed by the authors. Next, respondents rated on a series of 5-point Likert scales the helpfulness of several characteristics for identifying gay men and lesbians. Analysis supported the importance of eye contact for lesbians and gay men in identifying one another. For both lesbian and gay male participants, several other variables emerged as significantly helpful in identifying gay men: clothing style and fit, jewelry, facial expressions, posture, body type, walk or gait, and both the types and frequencies of gestures.     

Ethics education after licensing: ideas for increasing diversity in content and process

Continuing professional education in ethics for psychologists is becoming more common, as psychology licensing boards in 14 states now require continuing education in ethics as a condition of licensure renewal. This article suggests ways to improve the quality of ethics continuing education by diversifying the content and teaching methods.     

Awareness and working memory in strategy adaptivity

To further the understanding of the mechanisms of strategy choice, in three experiments, we investigate the role of explicit awareness and working memory in strategy adaptivity. Experiment 1 provided correlational evidence that individual differences in strategy adaptivity to changing base rates are related to individual differences in awareness of those changes but appear not to be related to individual differences in working memory capacity. Experiment 2 replicated the role of awareness, and the results suggest that awareness at the time of the base-rate change, rather than afterwards, is related to increased strategy adaptivity. Experiment 3 measured working memory capacity using a different procedure and manipulated working memory load with a dual-task procedure; again, no apparent role of working memory capacity in strategy adaptivity was found. This juxtaposition of findings presents a challenge for existing models of strategy choice.     

Accessing the Eternal: Dreaming "The Dreaming" and Ceremonial Performance

Australian Aboriginal cosmology is centered on The Dreaming, which has an eternal nature. It has been referred to as “everywhen” to articulate its timelessness. Starting with the assumption that “waking” reality is only one type of experienced reality, we investigate the concept of timelessness as it pertains to the Aboriginal worldview. We begin by questioning whether in fact “Dreaming” is an appropriate translation of a complex Aboriginal concept, then discuss whether there is any relationship between dreaming and The Dreaming. We then discuss Aboriginal ceremonial performance, during which actors are said to become Dreaming Ancestors, using as a frame of reference the “flow” experience explicated by Mihaly Csikszentmihalyi together with Alfred Schutz's “mutual tuning‐in relationship.”     

Developing a Framework for Assessing Responsible Conduct of Research Education Programs

Education in the responsible conduct of research (RCR) in the United States has evolved over the past decade from targeting trainees to including educational efforts aimed at faculty and staff. In addition RCR education has become more focused as federal agencies have moved to recommend specific content and to mandate education in certain areas. RCR education has therefore become a research-compliance issue necessitating the development of policies and the commitment of resources to develop or expand systems for educating faculty and staff and for assuring compliance. These changes implied the need to develop a program evaluation model that could be applied to institutional RCR education programs, which were expected to differ from traditional academic credit-bearing courses targeting trainees. Information gleaned from the examination of corporate compliance models was analyzed in order to create a program evaluation module that could be used to document and assess educational programs focused on teaching RCR. A programmed series of questions for each of the nine RCR content areas identified by the United States Office of Research Integrity was created based on a performance-monitoring evaluation model. The questions focus on educational goals, resources provided to support the educational efforts, educational content, content delivery, educational outcomes, compliance requirements and feedback. Answers collected in response to the questions could be used to both document and continually improve the quality of RCR educational programs through on-going formative assessment and feedback.     

The influence of family environment and child temperament on work/family role strain for mothers and fathers

This study examined the additive effect of structural variables, child characteristics, and the family environment on mothers' and fathers' work/family role strain. Differences between mothers and fathers on these variables were also examined. The sample consisted of 36 dualearner families whose children had been in daycare from infancy through 4 years of age. Structural variables included work schedules and time spent with child for mothers only, fathers only, and both parents together with child. Child characteristics included temperament and health. Family environment variables included different components of the family environment (conflict, cohesion, expressiveness, organization, and control) and parenting daily hassles. Results showed that mothers' time with child and caregiving for child were greater than fathers'. Mothers reported more expressiveness in the family and more daily hassles with children than fathers. Mothers' level of role strain was also significantly higher than fathers'. For mothers, role strain was associated with hours away from home, child sociability, family conflict, and daily hassles resulting in an R² of 0.57. Fathers' role strain was associated with family expressiveness, organization, and their wives' daily hassles resulting in an R² of 0.37. Data suggest that mothers' and fathers' role strain may be driven by somewhat different factors. For women, aspects of the family and the child and work hours accounted for a considerable portion of the variance while for men, only aspects of the family environment were associated with their level of role strain.
