To test or not to test: A clinical dilemma

This paper argues that clinicians are sometimes justified in not testing diagnoses or in not subjecting them to a full battery of tests. In deciding whether to conduct a test, a clinician may consider and weigh several different factors, including her confidence in her initial diagnosis, the specificity and sensitivity of the test, the consequences of making a false diagnosis, the pain, harm, and inconvenience caused by the test, and the costs of the test to the patient and society. This view suggests that diagnoses are fundamentally different from scientific hypotheses in that they are not always subjected to the same evidential standards.     

To share or not to share: The place of personal disclosure in scholarly writing

The norms of scholarly discourse have traditionally excluded personal disclosures in conceptual articles, as if the subjective nature of such revelations would be inconsistent with the scientific/objective stature of these works. Based on the author's experience with a recent publication, based on recent studies of researcher projection and bias in case studies, and using a framework of organizational communication, it is suggested here that there is indeed a contribution such disclosures can make. It is not recommended that sharing on a personal level become a new norm, but rather that the choice to share be considered as viable in a scholarly context. Five specific benefits of such sharing are listed, including unearthing and revealing bias, demystifying the process of discovery, and avoiding the trap of defensive reasoning.     

Distal rhythm influences whether or not listeners hear a word in continuous speech: Support for a perceptual grouping hypothesis

Due to extensive variability in the phonetic realizations of words, there may be few or no proximal spectro-temporal cues that identify a word’s onset or even its presence. Dilley and Pitt (2010) showed that the rate of context speech, distal from a to-be-recognized word, can have a sizeable effect on whether or not a word is perceived. This investigation considered whether there is a distinct role for distal rhythm in the disappearing word effect. Listeners heard sentences that had a grammatical interpretation with or without a critical function word (FW) and transcribed what they heard (e.g., are in Jill got quite mad when she heard there are birds can be removed and Jill got quite mad when she heard their birds is still grammatical). Consistent with a perceptual grouping hypothesis, participants were more likely to report critical FWs when distal rhythm (repeating ternary or binary pitch patterns) matched the rhythm in the FW-containing region than when it did not. Notably, effects of distal rhythm and distal rate were additive. Results demonstrate a novel effect of distal rhythm on the amount of lexical material listeners hear, highlighting the importance of distal timing information and providing new constraints for models of spoken word recognition.     

Personality in the age of industry: Structure,heritability, and correlates of personality in middle childhood from the perspective of parents,teachers, and children

Middle childhood is a crucial juncture in the lifespan where children work toward achieving a sense of competence foundational for future development. However, middle childhood has historically been underrepresented in the personality literature. The current study provides a comprehensive examination of personality in middle childhood using a large (N = 2510), longitudinal sample of 10- to 12-year-old twins. The structure, heritability, and correlates of personality in this period were investigated using personality ratings of parents, teachers, and children. Results showed that personality in middle childhood has a coherent structure, is heritable, and is relevant for developmentally salient outcomes such as externalizing behavior, substance use, and academic engagement. Results emphasize the importance of investigating personality in middle childhood across multiple informants.     

Behavior modification in the home: Siblings as behavior modifiers,parents as observers

It was hypothesized that siblings could function as effective behavior change agents for their behaviorally disturbed brothers and sisters within the home environment. Further, it was predicted that parents could be trained to be reliable observers of their children's performance under these circumstances. The results of the study supported both predictions with siblings in two separate families demonstrating their ability to work with their brother or sister within the context of an ABAB reversal design. Parents were also shown to obtain consistently high reliability ratings when compared to outside observers. The judicious use of siblings as behavior modification aides is recommended as a treatment procedure.     

Vibrotactile localization on the arm: effects of place, space, and age

Although tactile acuity has been explored for touch stimuli, vibrotactile resolution on the skin has not. In the present experiments, we explored the ability to localize vibrotactile stimuli on a linear array of tactors on the forearm. We examined the influence of a number of stimulus parameters, including the frequency of the vibratory stimulus, the locations of the stimulus sites on the body relative to specific body references or landmarks, the proximity among driven loci, and the age of the observer. Stimulus frequency and age group showed much less of an effect on localization than was expected. The position of stimulus sites relative to body landmarks and the separation among sites exerted the strongest influence on localization accuracy, and these effects could be mimicked by introducing an "artificial" referent into the tactile array.     

Evaluations by staff, residents, and community seniors of patronizing speech in the nursing home: impact of passive, assertive, or humorous responses

Two studies tested the impact of alternative communication in accommodation strategies. Nursing home staff and residents (and community-residing seniors in Study 2) rated nurse-resident conversational scenarios in which a resident responded passively, directly assertively, or humorously (indirectly assertively) to a patronizing nurse. The nurse then either maintained a patronizing manner or accommodated with a more respectful speech style. Even though all groups devalued the nurse who maintained a patronizing speech style, nursing home residents predictably showed the most acceptance. The directly assertive response by the resident elicited more devaluation of the nonaccommodating nurse than did either passive or humorous responses, but also the least favorable ratings of the resident. Ratings of the humorous response in Study 2 suggested that humor could be a good compromise response style for allowing the receiver of patronizing speech to express opposition to a request, yet still maintain an appearance of competence and politeness.     

Searle on Consciousness: or How not to Be a Physicalist

In The Rediscovery of the Mind , John Searle offers a novel theory of consciousness that attempts to overcome the traditional debates within the philosophy of mind between dualism and materialism. Searle maintains that one can be a thoroughgoing materialist without denying the existence of mental phenomena that are inherently subjective in nature. In this paper I argue that Searle's view does not so easily bypass the traditional philosophical debate between materialism and dualism, and, indeed, that Searle's attempt to have it both ways is inconsistent. More specifically, I examine Searle's discussion of the causal reducibility of consciousness and his claim that consciousness is just another property of certain biological systems and argue that in both cases Searle has failed to show that consciousness can be both irreducibly subjective and a normal physical feature of the brain.     

To stay or to go, to speak or stay silent, to act or not to act: moral distress as experienced by psychologists

The moral distress of psychologists working in psychiatric and mental health care settings was explored in an interdisciplinary, hermeneutic phenomenological study situated at the University of Alberta, Canada. Moral distress is the state experienced when moral choices and actions are thwarted by constraints. Psychologists described specific incidents in which they felt their integrity had been compromised by such factors as institutional and interinstitutional demands, team conflicts, and interdisciplinary disputes. They described dealing with the resulting moral distress by such means as silence, taking a stance, acting secretively, sustaining themselves through work with clients, seeking support from colleagues, and exiting. Recognizing moral distress can lead to a significant shift in the way we perceive moral choices and understand the moral context of practice.     

Direct assessment of quality of care in a geriatric nursing home

Direct observation was used to examine multiple aspects of care provided in a proprietary nursing home. The samples were taken at random intervals, 7 days per week for 5 weeks, across several categories of environmental and resident conditions as well as staff and resident activity. Results showed a high degee of compliance with predefined standards (based on current federal regulations) for environmental and resident conditions. Overall distributions of resident and staff activity showed results similar to those found in previous studies, with residents spending most of their time engaged in nonsocial activity and staff spending the majority of their time engaged in nonresident work. When data were analyzed across areas of the facility, times of day, and weekdays versus weekends, some differences were noted. Weekend versus weekday comparisons showed higher resident:staff ratios on weekends and more resident inactivity, but no significant differences in environmental or resident conditions. In addition, more frequent resident care, resident interaction, and resident activity were observed in Medicare units than in non-Medicare units. Results are discussed in terms of federal requirements for monitoring the quality of care in nursing homes and the potential use of time sampling expressly for this purpose.     

Inducing disbelief in free will alters brain correlates of preconscious motor preparation: the brain minds whether we believe in free will or not

The feeling of being in control of one's own actions is a strong subjective experience. However, discoveries in psychology and neuroscience challenge the validity of this experience and suggest that free will is just an illusion. This raises a question: What would happen if people started to disbelieve in free will? Previous research has shown that low control beliefs affect performance and motivation. Recently, it has been shown that undermining free-will beliefs influences social behavior. In the study reported here, we investigated whether undermining beliefs in free will affects brain correlates of voluntary motor preparation. Our results showed that the readiness potential was reduced in individuals induced to disbelieve in free will. This effect was evident more than 1 s before participants consciously decided to move, a finding that suggests that the manipulation influenced intentional actions at preconscious stages. Our findings indicate that abstract belief systems might have a much more fundamental effect than previously thought.     

Reactivity to home observation: a comparison of audio recorded behavior with observers present or absent

THE STUDY COMPARED THE BEHAVIOR OF FAMILY MEMBERS AT HOME AS RECORDED BY AUDIOTAPE RECORDINGS IN TWO CONDITIONS: with an observer present or absent. Behavioral differences were expected as a function of differential reactivity to these observational procedures, but none was found, and there was no evidence of adaptation effects in either condition. In general, significant positive correlations were obtained between the rates of recorded behavior in both situations. The implications of these findings for the development of nonreactive observation procedures were discussed.     

My place,your place,and no place: Behavior settings as a risk factor for HIV-related injection practices of drug users in Baltimore,Maryland

Information is sparse on the social context of illicit drug injection behaviors and their relationship to HIV infection. This study examined relationships between injection settings, injecting with others, and HIV risk behaviors of sharing needles and not cleaning contaminated needles in a sample of 630 inner-city injecting drug users in Baltimore, MD. Through open-ended interviews, five primary settings of injection behavior were identified. These settings included one's own, friends' and mother's residence, shooting galleries, and semipublic areas. Most participants reported injecting in their own residence (92%) and friends' residence (86%) in the prior 6 months. In a multiple regression analysis, injecting at friends' residence, in shooting galleries, and in semipublic areas and frequency of injecting with others were significantly associated with frequency of sharing uncleaned needles, “slipping” (i.e., failure to disinfect shared needles), and not always cleaning used needles before injecting. Results suggest that interventions may benefit from targeting settings as well as behaviors to reduce the spread of HIV. This research was supported by grants DA04334, DA05911, DA06313, and DA08985 from the National Institute on Drug Abuse.     

Up and down in middle age: monotonic and nonmonotonic changes in roles, status, and personality

It is proposed that personality (conceptualized in terms of motives and psychological resources) changes normatively not only from young adulthood to middle age but also within middle age and that these changes take place in relation to social and biosocial change over the same period. Data from 123 women studied at ages 27, 43, 52, and 61 largely supported hypotheses about change in social roles, status, health, motives, personality characteristics, emotion regulation, and relationships. Noteworthy aspects of the findings were substantial curvilinear change within middle age and associations of work involvement and physical health with personality change during late middle age.
