Adolescent diet, physical activity and nutritional status are generally known to be sub-optimal. This is an introduction to a special issue of papers devoted to exploring factors affecting diet and physical activity in adolescents, including food insecure and vulnerable groups.

Eight settings including urban, peri-urban and rural across sites from five different low- and middle-income countries.

Focus groups with adolescents and caregivers carried out by trained researchers.

Our results show that adolescents, even in poor settings, know about healthy diet and lifestyles. #link# They want to have energy, feel happy, look good and live longer, but their desire for autonomy, a need to 'belong' in their peer group, plus vulnerability to marketing exploiting their aspirations, leads them to make unhealthy choices. They describe significant gender, culture and context-specific barriers. For example, urban adolescents had easy access to energy dense, unhealthy foods bought outside the home, whereas junk foods were g Adolescent Lives through Nutrition consortium will employ groups of adolescents, caregivers and local stakeholders in each site to develop interventions to improve adolescent nutritional status.Presenting items multiple times on a study list increases their memorability, a process known as item strengthening. The list-strength effect (LSE) refers to the finding that, compared to unstrengthened (pure) lists, lists for which a subset of the items have been strengthened produce enhanced memory for the strengthened items and depressed memory for the unstrengthened items. Although the LSE is found in free recall (Tulving & Hastie, 1972), it does not occur in recognition (Ratcliff et al., 1990). In free recall, the LSE in mixed lists is attributed to a sampling bias promoting priority recall of strong items and consequent output interference affecting weak items. We suggest that, in recognition, the disruption of this pattern through the randomization of test probes is responsible for the null LSE. We present several pilot experiments consistent with this account; however, the registered experiment, which had more statistical power, did not support this account.When gently stroked with velocities between 0.1 and 30 cm/s, participants typically rate velocities around 3 cm/s as most pleasant, and the ratings follow an inverted u-shape. This pleasantness curve correlates often, but not always, with the firing rate of unmyelinated C-tactile (CT) afferents, leading to the notion that CT afferents code for the hedonic or emotional aspect of gentle touch. However, there is also evidence that CT firing does not necessarily equal pleasantness, and the range of attributes that CT afferents code for is not known. Here, participants were stroked with different velocities assumed to activate CT afferents to a different extent while they rated the touch on several sensory and emotional attributes. Transmembrane Transporters inhibitor expected an inverted u-shaped rating curve for pleasantness and other emotional attributes, but not for sensory attributes. Inverted u-shaped rating patterns were found for the emotional attributes "pleasant" and "not burdensome," but also for the sensory attribute "rough." CT-directed stimulation is thus not only experienced as hedonic. The sensations arising from CTs together with all other types of mechanoreceptors might be centrally integrated into a percept that represents those aspects which are most salient for the stimulation at hand.The actions associated with objects are thought to be automatically activated when processing object names. Recent studies, however, have failed to find evidence for a role of the motor system in long-term memory for objects. One exception is a study by van Dam et al. (2013) in which participants studied object names associated with pressing (e.g., doorbell) or twisting (e.g., jar), followed by pressing or twisting actions in a seemingly unrelated task. In the final memory test, performance for action congruent words was better than for action incongruent words. We aimed to generalize these findings. In Experiments 1 and 2, we found no effect of action congruency on repetition priming in lexical decision and man-made/natural decision. In Experiment 3, the action congruency manipulation was administered immediately after initial study or a day later, just prior to the recognition memory test. We found no effects of action congruency and timing of the action. Finally, Experiment 4 was a direct replication of Experiment 1 of van Dam et al. (2013). Again, we failed to find an effect of poststudy action congruency. Thus, we obtained no evidence for the view that motor actions play a role in long-term memory for objects.Concealing memories and emotions associated with a traumatic event seems to have negative effects on health. Re-enacting those events through writing is an opportunity to disclose such memories and emotions, and especially for emotion regulation. To study this, 57 university students were randomly assigned to one of two groups. They either completed an expressive writing or a neutral writing task. Real-time writing and psychophysiological data were recorded throughout the experiment to examine writing dynamics associated with emotion regulation and its psychophysiological correlates (electrodermal activity and electrocardiography measures). The results showed that the expressive group (EG) paused for longer than the control group (CG) denoting a positive and medium effect size ( η p 2 = .10 ) . Furthermore, during and after writing, the EG showed a higher low frequency/high frequency ratio than the CG, evidencing a positive and large effect size ( η p 2 = .22 ) . These real-time findings are interpreted as signs of emotion regulation happening during writing.Visual input of a face appears to influence the ability to selectively attend to one voice over another simultaneous voice. We examined this crossmodal effect, specifically the role face gender may have on selective attention to male and female gendered simultaneous voices. Using a within-subjects design, participants were presented with a dynamic male face, female face, or fixation cross, with each condition being paired with a dichotomous audio stream of male and female voices reciting different lists of concrete nouns. In Experiment 1a, the female voice was played in the right ear and the male voice in the left ear. In Experiment 1b, both voices were played in both ears with differences in volume mimicking the interaural intensity difference between disparately localized voices in naturalistic situations. Free recall of words spoken by the two voices immediately following stimulus presentation served as a proxy measure of attention. In both sections of the experiment, crossmodal congruity of face gender enhanced same-gender word recall.
