Multiple studies and systematic reviews have shown that music instruction improves phonological awareness (PA) and early literacy skills in children, although findings vary. In meta-analyses, the reliability and significance of the transfer effect are reduced. The study evaluated the effect of varying durations of music instruction exposure, over a single academic year, on PA and early literacy of young children. Based on the exposure to music instruction, participants were assigned to either a low- or high-exposure group. Additional analyses were conducted for 17 age-matched pairs and to compare participants that only received class music to those that received additional music instruction. Between-groups comparisons showed no significant difference after a single academic year of music instruction. Within-groups comparisons identified more PA improvements in the high-exposure group. Exposure to music instruction for no less than one academic year, is required to conclusively evaluate the effect on PA and early literacy.

Recent years have seen a marked increase in carbon emissions despite pledges made by the international community at the Paris Accord in 2015 to reduce fossil fuel production and consumption. Rebound effects could contribute to this phenomenon as, in which attempts to curb carbon emissions might have inadvertently led to an upswing in fossil fuel usage. The present study hypothesizes that rebound effects are driven by a misapplication of compensatory balancing heuristics, with the unintended outcome of producing inaccurate estimates of the environmental impact of “green” or environmentally friendly labelled products or behaviors. The present study therefore aims to investigate the relationship between participants’ degree of compensatory thinking (e.g., “Recycling compensates for driving a car”) and their susceptibility to the Negative Footprint Illusion, a widely replicated phenomenon demonstrating that the presence of “green” products biases carbon footprint estimations. One hundred and twelve participants were asked to complete a 15-item Compensatory Green Beliefs scale and to estimate the total carbon footprint of a set of 15 conventional houses, followed by a set that included 15 “green” houses in addition to 15 conventional houses. Results indicated that participants, on average, believed that the “green” houses were carbon neutral, and that susceptibility to the Negative Footprint Illusion was predicted by performance on the Compensatory Green Beliefs scale. This is the first study confirming that individual differences in cognitive processes (i.e., Compensatory Green Beliefs) are indeed related to inaccurate estimates of “green” products, providing a foundation for further investigation of the influence of “green” and compensatory beliefs on carbon footprint estimates.

Purpose: Working memory capacity and language ability modulate speech reception; however, the respective roles of peripheral and cognitive processing are unclear. The contribution of individual differences in these abilities to utilization of spatial cues when separating speech from informational and energetic masking backgrounds in children has not yet been determined. Therefore, this study explored whether speech reception in children is modulated by environmental factors, such as the type of background noise and spatial configuration of target and noise sources, and individual differences in the cognitive and linguistic abilities of listeners. Method: Speech reception thresholds were assessed in 39 children aged 5–7 years in simulated school listening environments. Speech reception thresholds of target sentences spoken by an adult male consisting of number and color combinations were measured using an adaptive procedure, with speech-shaped white noise and single-talker backgrounds that were either collocated (target and back-ground at 0°) or spatially separated (target at 0°, background noise at 90° to the right). Spatial release from masking was assessed alongside memory span and expressive language. Results and Conclusion: Significant main effect results showed that speech reception thresholds were highest for informational maskers and collocated conditions. Significant interactions indicated that individual differences in memory span and language ability were related to spatial release from masking advantages. Specifically, individual differences in memory span and language were related to the utilization of spatial cues in separated conditions. Language differences were related to auditory stream segregation abilities in collocated conditions that lack helpful spatial cues, pointing to the utilization of language processes to make up for losses in spatial information.

The benefits in speech-in-noise perception, language and cognition brought about by extensive musical training in adults and children have been demonstrated in a number of cross-sectional studies. Therefore, this study aimed to investigate whether one year of school-delivered musical training, consisting of individual and group instrumental classes, was capable of producing advantages for speech-in-noise perception and phonological short-term memory in children tested in a simulated classroom environment. Forty-one children aged 5–7 years at the first measurement point participated in the study and either went to a music-focused or a sport-focused private school with an otherwise equivalent school curriculum. The children’s ability to detect number and color words in noise was measured under a number of conditions including different masker types (speech-shaped noise, single-talker background) and under varying spatial combinations of target and masker (spatially collocated, spatially separated). Additionally, a cognitive factor essential to speech perception, namely phonological short-term memory, was assessed. Findings were unable to confirm that musical training of the frequency and duration administered was associated with a musicians’ advantage for either speech in noise, under any of the masker or spatial conditions tested, or phonological short-term memory.

Purpose: Phonological awareness (PA) requires the complex integration of language, speech, and auditory processing abilities. Enhanced pitch and rhythm discrimination have been shown to improve PA and speech-in-noise (SiN) discrimination. The screening of pitch and rhythm discrimination, if nonlinguistic correlates of these abilities, could contribute to screening procedures prior to diagnostic assessment. This research aimed to determine the association of PA abilities with pitch, rhythm, and SiN discrimination in children aged 5-7 years old. Method: Forty-one participants' pitch, rhythm, and SiN discrimination and PA abilities were evaluated. To control for confounding factors, including biological and environmental risk exposure and gender differences, typically developing male children from high socioeconomic statuses were selected. Pearson correlation was used to identify associations between variables, and stepwise regression analysis was used to identify possible predictors of PA. Results: Correlations of medium strength were identified between PA and pitch, rhythm, and SiN discrimination. Pitch and diotic digit-in-noise discrimination formed the strongest regression model (adjusted R-2 =.4213, r =.649) for phoneme-grapheme correspondence. Conclusions: The current study demonstrates predictive relationships between the complex auditory discrimination skills of pitch, rhythm, and diotic digit-in-noise recognition and foundational phonemic awareness and phonic skills in young males from high socioeconomic statuses. Pitch, rhythm, and digit-in-noise discrimination measures hold potential as screening measures for delays in phonemic awareness and phonic difficulties and as components of stimulation programs.

Populations in cities are projected to increase globally, densifying urban residential environments with both positive and negative effects. Positive social effects are offset by negative health effects however; urban residential noise has been identified in a large number of studies as a significant contributor to social unrest as well as a risk to physiological and psychological health caused by stress, making this topic highly relevant to the discussion on sustainability urban growth. Focusing on the psychological rebound effect of urban residential noise, this paper attempts to explain how and why auditory aspects of the spatial environment negatively influences urban residents. To provide context and to indicate areas in need of improvement, the legislative challenges to be faced are considered, with Sweden as a prime example of a first world country grappling with the effects of increased urban density. Existing building legislation regarding residential noise is considered in relation to studies investigating the effects of residential noise on psychological and physiological health, outlining areas in need of future development. Then, health responses to residential noise are placed in a broader evolutionary context by considering how these effects might be the result of triggered evolutionary mechanisms for keeping population size optimal. Further, the spatial dimension of hearing is discussed with reference to theories of territoriality in environmental psychology and the concept of auditory territoriality is described.
