Token Economies: Using Basic Experimental Research to Guide Practical Applications

This paper highlights the applicability of patterns seen within basic experimental research in relation to contemporary application of token economies. Token economies are one of the most widely used interventions to promote behavior change, and this procedure has evolved to be effective across many settings, behaviors, and individuals. Due to this widespread use, casual implementation of the token economy might result in inconsistencies in responding and therefore an overall skepticism in the procedure itself. We present multiple barriers that encumber practical application of token economies, including insufficient conditioning and pairing of tokens, determining quality of backup reinforcers, unforeseen effects of motivating operations, teaching the token exchange, effects of higher-order reinforcement schedules, ratio strain, and use of response cost procedures. To assist practitioners in implementing more effective treatments, for each barrier we revisit the often overlooked basic research involving features of conditioned reinforcement and reinforcement schedules. It is important to translate the often complex implications of basic research so that practitioners can use this information to improve their own practice as well as their confidence in disseminating use of this evidence-based treatment. To further guide practitioners in using this knowledge in everyday settings, we also provide recommendations specific to each barrier as well as relevant applied research and practical examples.     

Action observation produces motor resonance in Parkinson's disease

Observation of movement activates the observer's own motor system, influencing the performance of actions and facilitating social interaction. This motor resonance is demonstrated behaviourally through visuomotor priming, whereby response latencies are influenced by the compatibility between an intended action and an observed (task‐irrelevant) action. The impact of movement disorders such as Parkinson's disease (PD) on motor resonance is unclear, as previous studies of visuomotor priming have not separated imitative compatibility (specific to human movement) from general stimulus‐response compatibility effects. We examined visuomotor priming in 23 participants with mild‐to‐moderate PD and 24 healthy older adults, using a task that pitted imitative compatibility against general stimulus‐response compatibility. Participants made a key press after observing a task‐irrelevant moving human finger or rectangle that was either compatible or incompatible with their response. Imitative compatibility effects, rather than general stimulus‐response compatibility effects, were found specifically for the human finger. Moreover, imitative compatibility effects did not differ between groups, indicating intact motor resonance in the PD group. These findings constitute the first unambiguous demonstration of imitative priming in both PD and healthy ageing, and have implications for therapeutic techniques to facilitate action, as well as the understanding of social cognition in PD.     

Should They Be Recruited? Fan Perceptions of Deviant Student-Athletes

The purpose of this study was to examine fan opinion toward the active recruitment of prospective student-athletes with deviant pasts. College football fans were surveyed to determine to what extent the deviant behavior of a prospective student-athlete impacted how much they would support their favorite team recruiting that athlete. There were three primary findings: (a) deviant behavior negatively impacts a prospective student-athlete’s fan support score, (b) assault of a female student is the most severe deviant behavior in which an athlete could engage, and (c) White recruits were judged more harshly for using illegal drugs when compared to Black recruits.     

Qualitative Investigation of Student Reflections on a Spiritual/Religious Diversity Experience

Twenty‐six master's‐level counselor education students participated in a spiritual and religious diversity assignment, which involved participation in a spiritual or religious activity for 5 weeks. Participants then discussed these experiences in reflection papers. After analysis of the student papers, the authors identified the following themes: (a) discomfort related to the experience, (b) initial assumptions regarding spirituality and religion, (c) movement toward appreciation of spiritual and religious diversity, (d) increases in self‐understanding, (e) the value of experiential learning, and (f) motivation for additional learning. The authors provide suggestions for counselor training on spirituality and religion.     

Computation of cone contrasts for color vision research

Cone-contrast coordinates have proved useful for representing transient test stimuli used in color vision experiments. These representations automatically take into account the spectral absorption of cones and any Weberian adaptation to steady fields of light. Under these conditions, they also can be interpreted as being an approximation to the incremental cone response. A detailed methodology is presented for making appropriate measurements and calculations of cons contrasts for any light source, especially color monitors.     

The golem: Uncertainty and communicating science

This paper elaborates on the golem metaphor as a way of understanding uncertainty in science. Its implications for the ethics of communicating science are explored.     

Implicit and explicit tests of odor memory reveal different outcomes following interference

Experiencing two odors as a mixture can later increase their perceived similarity when presented separately. Such an increase in similarity can be used as an implicit measure of how well participants remember the mixture. Three experiments tested the resistance to interference of this effect by first giving participants exposure to two 2-odor mixtures and then presenting each odor from one mixture (interfered pair) separately many times. After the latter interference phase, participants rated the similarity of the two odors in each pair. The experiments varied in terms of the number of initial exposures to the mixtures, the number of odor presentations in the interference phase, and the control conditions employed. No difference in similarity ratings for the interfered and non-interfered pair was found in any experiment. In contrast to the lack of interference with this implicit measure, an explicit measure of memory based on participants’ ratings of odor frequency revealed that they could recall to some degree that the interfered odors had been presented alone in the second phase. These results suggest that implicit memory for odor mixtures is highly resistant to interference and is consistent with a configural encoding account of this effect.     

Dehumanizing but competent: The impact of gender,illness type,and emotional expressiveness on patient perceptions of doctors

This study is the first attempt to investigate men's and women's anticipated reactions to a consultation with a doctor holding either a dehumanizing or humanistic approach to patient treatment. Participants (N = 375) read a vignette depicting a doctor's treatment philosophy—emphasizing either the metaphor of the body as a machine (dehumanizing condition) or emphasizing individual humanness (humanizing condition). They then imagined consulting the doctor about a psychological or physical illness. Although, medical dehumanization had undesirable consequences, some men rated the dehumanizing doctor as more competent than the humanizing doctor. These were men who were (a) emotionally expressive and seeking help for a psychological illness, and (b) men low in emotional expressiveness seeking help for a physical illness.
