Pitch Range Variations Improve Cognitive Processing of Audio Messages

This study explores the effect of different speaker intonation strategies in audio messages on attention, autonomic arousal, and memory. In this study, participants listened to 16 radio commercials, produced to vary in pitch range across sentences. Dependent variables were self‐reported effectiveness and adequacy, psychophysiological arousal and attention, immediate word recall and recognition of information. Results showed that messages conveyed with pitch variations achieved better scores compared to commercials with a homogenous pitch range across the sentences. This was especially the case when high pitch intonation was followed by low pitch within a sentence. The results increase our understanding of the influence of pitch range on processing by establishing a concrete strategy as a best practice for improving attention and memory.     

Maximization and Search for Alternatives in Decision Situations With and Without Loss of Options

Maximizing tendency has been associated with greater accumulation of choice alternatives prior to selection of a preference. It is not known whether this search behavior extends to situations in which accumulation of new choice alternatives comes with the potential loss of existing ones. In Study 1, we replicate the original finding of greater accumulation of choice alternatives, using a computer‐based laboratory task. We then provide evidence, in Studies 2 and 3, that when potential loss of existing options is incorporated into the task, maximization is associated with less rather than more search for additional options. Maximization components of decision difficulty and alternative search, but not high standards or satisficing, explain this behavior. Other task measures are also collected, but few maximization‐related differences are observed. The findings support an interpretation of maximizers as decision makers who are as concerned with the potential loss of existing options as with the loss of undiscovered future ones.

Parenting a Child with Phenylketonuria (PKU): an Interpretative Phenomenological Analysis (IPA) of the Experience of Parents

Phenylketonuria (PKU) is a rare inherited metabolic disorder which can cause neurological damage if left untreated. PKU is identified through newborn screening in developed countries, and treatment begins immediately to prevent these severe consequences. When a child is diagnosed, parents must assume immediate responsibility for the management of PKU and prevention of neurological damage. Quantitative studies have identified significant psychosocial stressors for parents, but little is known about how the parents experience this process. This study aimed to explore the experiences of parents of children with PKU under the age of two. It is the first study to examine these experiences in this way. Seven parents were interviewed about their experiences, and interpretative phenomenological analysis was used to analyse the data. Three main themes were identified: control, striving for normality and acceptance of PKU as a continuum. Links between the themes and processes underpinning the results were explored with relation to existing literature and theories from a clinical psychology perspective. The role of acceptance of PKU was central to the parent’s experiences. Clinical implications and suggestions for further research are discussed.     

Implementing Group CBT for Depression Among Latinos in a Primary Care Clinic

Depression in low-income Latino populations can be treated using group cognitive behavioral therapy (GCBT). However, effective delivery of GCBT for depression in primary care settings is often impeded by high dropout rates and poor homework adherence. In this study, we describe the structure, processes, and outcomes (including attendance, homework completion, and symptom measures) of GCBT for Spanish-speaking Latino patients with depression in an urban public sector primary care setting. For this study, 96 Latino patients in a primary care clinic participated in at least 1 session of GCBT. Although depressive symptoms among these patients, as measured by the PHQ-9, significantly decreased during treatment, attendance and homework completion were limited. Even with a strategy in place to allow patients to continue in treatment after missing several sessions, 23% of patients dropped out of therapy following their initial session, and approximately half of all patients completed less than 50% (or 8) therapy sessions. Homework was only completed 23% of the time it was checked. Greater session attendance prospectively predicted lower depressive symptoms over time. We discuss potential strategies to increase engagement, treatment effects, and symptom reduction for depression in primary care settings.     

Proactive vitality management in the work context: development and validation of a new instrument

In the present research, we use proactivity literature and studies on energy at work to argue that individuals may proactively manage their vitality (i.e., physical and mental energy) to promote optimal functioning at work. We develop and validate a scale to measure proactive vitality management (PVM), and explore the nomological network. We conducted a five-day diary study (N = 133; 521 days), a survey study (N = 813) and a cross-sectional study measuring daily PVM (N = 246) among working individuals from various occupational sectors. The results show that PVM can be reliably measured with eight items that load on one overall factor, both on general and daily level. Furthermore, daily PVM was moderately but positively related to the use of work-related strategies and micro-breaks. Moreover, PVM related positively to relevant personal characteristics (i.e., proactive personality and self-insight) and showed moderate but positive relationships with job crafting and relaxation (convergent validity). PVM was unrelated to psychological detachment and decreasing hindering demands (discriminant validity). Finally, PVM was positively related to well-being, in-role work performance, creative work performance and performance on the Remote Associates Test (criterion validity). We conclude that employees may promote their own work performance through the use of PVM.     

Interpersonal movement synchrony facilitates pro‐social behavior in children's peer‐play

The emergence of pro‐social behaviors and social interaction skills is a major focus of research on children's development. Here, we consider one important feature of human social interactions, interpersonal movement synchrony, and explore its effects on pro‐sociality among young children. Coordinated movements are a crucial part of mother–infant interactions, with important social effects extending well into childhood. Musical interactions are also known to facilitate bonding between infants and caretakers and pro‐sociality among peers. We specifically examine the pro‐social effects of interpersonal movement synchrony in a naturalistic peer‐play context among 4‐ to 6‐year‐old children. We assessed the amount of helping behavior between pairs of children following an activity that they performed synchronously or non‐synchronously. Children who engaged in synchronous play, as compared with non‐synchronous play, showed significantly more subsequent spontaneous helping behavior. Further, more mutual smiling and eye contact were observed in the synchronous condition and amounts of mutual smiling and eye contact during the movement task correlated with amount of helping behavior observed. Neither measure mediated the condition‐wise effects on helping, however. These results are discussed in terms of their contribution to existing literature and their broader implications for the development of pro‐sociality and coordinated movements in early childhood.     

The impact of aging on associative memory for preexisting unitized associations

Aging is accompanied by a decline in associative memory that can, however, be attenuated when associations are unitized at encoding, that is, when they form an integrated entity. Unitization is thought to promote familiarity-based recognition memory, which is preserved in aging. We examined whether preexperimentally unitized associations (compound words (CWs)) do indeed reduce age differences in memory, and whether preexperimental unitization promotes familiarity. In Experiment 1, we assessed the memory of 20 young and 20 older participants for compound versus unrelated word pairs using a yes/no recognition test with Remember/Know/Guess judgments. In Experiment 2, we tested 20 young and 20 older participants using the same procedure, except for the use of a two-alternative forced-choice recognition paradigm, which is thought to enhance the contribution of familiarity. The results of both experiments corroborated the greater contribution of familiarity to recognition of unitized associations. In Experiment 1, however, the use of CWs did not attenuate the age-related associative decline. We suggest that preexisting knowledge associated with recombined compounds induced high absolute familiarity and illusory recollection, leading to high false-recognition rates for the older adults. By contrast, the two groups performed similarly across both conditions in Experiment 2. Thus, the forced-choice procedure facilitates the use of familiarity in such a way that it improves older adults’ associative memory to the level of young participants. These results suggest that the modulation of associative memory in aging by preexisting unitization varies according to methodological parameters, such as the nature of the lures and the test format.
