EARLY PARENTING SUPPORT AND INFORMATION: A CONSUMER PERSPECTIVE

The transition to parenthood is a period of both joy and challenge for most parents. There is a recognized need to support parents during this period, yet existing interventions have shown limited evidence of efficacy. This study takes a consumer‐focused approach to examine the needs and preferences of parents both prenatally (n = 77) and postnatally (n = 123) for parenting support. The study used a cross‐sectional design with a purpose‐built online survey. Parents were recruited via online forums, Facebook and parenting blogs, childcare centers, and playgroups. In general, all parents were satisfied with their current levels of both formal and informal support, and about one fourth of parents had accessed a parenting intervention. Parents expressed a moderate level of interest in additional parenting information, and parents expecting their first baby indicated preferences for information about basic baby care needs whereas postnatally, parents expressed more interest in topics around self‐care and behavior management. The implications for developing interventions and engaging families are discussed.     

Direct remembering,mediated remembering,and atypical forgetting functions

Atypical forgetting functions have been demonstrated in several recent studies of delayed matching to sample, in which experimental conditions are altered partway through the retention interval. The forgetting functions are atypical in that accuracy or discriminability is not always a negatively accelerated monotonic function of increasing retention interval duration, but may increase at later times in the retention interval. Atypical forgetting functions reflect changes in levels of discrimination. A switch from a lower level to a higher level of discrimination, or vice versa, can occur at any time in the retention interval. The behavioral theories of remembering proposed by Nevin, Davison, Odum, and Shahan (2007), and White and Brown (2014), offer quantitative predictions of forgetting functions that differ in intercept or slope. Both theories are able to account for atypical forgetting functions, by assuming time‐independent changes in the mediating effect of attending to sample and comparison stimuli (in Nevin et al.'s model) or in the direct effect of the context of reinforcement of the conditional discrimination (in White & Brown's model). Despite differences in their main assumptions, the theories have an edge over any theory that assumes that forgetting is time‐dependent.     

An evaluation of a visual–visual successive matching‐to‐sample procedure to establish equivalence classes in adults

Traditionally, behavior analysts have studied stimulus equivalence using a matching‐to‐sample (MTS) preparation. Although researchers have shown the utility of MTS to yield equivalence classes, the procedure requires several prerequisite skills for a learner to accurately respond. Previous research with humans and nonhumans has shown that relational responding can be produced via compound stimulus discrimination and successive matching‐to‐sample (S‐MTS). We conducted four experiments with college students to further evaluate the effectiveness of S‐MTS in the establishment of stimulus relations. S‐MTS trials consisted of the presentation of a single sample stimulus followed by one comparison in a fixed location on a computer screen. Depending upon the sample–comparison relation, participants touched (i.e., go) or did not touch (i.e., no‐go) the comparison stimulus. Following training of the baseline relations (AB/BC), we assessed the emergence of symmetry, transitivity, and equivalence performances (i.e., BA/CB and AC/CA). Results support the utility of the S‐MTS procedure as a possible alternative to traditional MTS. This study has direct implications for participants for whom traditional three‐array MTS procedures may be challenging.     

On the Moral Significance of Sacrifice

ABSTRACT

The paper offers a few reflections on moral implications of making sacrifices and on possible duties to make sacrifices. It does not provide an exhaustive or a systematic account of the subject. There are too many disparate questions, and too many different perspectives from which to examine them to allow for a systematic let alone an exhaustive account, and too many factual issues that I am not aware of. Needless to say, the observations that follow are in part stimulated by the popularity of some views that are mistaken. I will not however examine any specific view or account of these matters. The aim is to provide some pointers that will be helpful when considering specific issues regarding the moral significance of sacrifice.     

Equivalence class formation as a function of preliminary training with pictorial stimuli

The present experiment investigated the effects of preliminary training with pictorial stimuli on the subsequent formation of three 5‐member equivalence classes (A?B?C?D?E) in 84 university students assigned to seven groups of 12. In the Abstract (ABS) group, all stimuli were abstract shapes. In the Picture (PIC) group, the C stimuli were pictures, and the remaining stimuli were the same abstract shapes as in the ABS group. For the remaining five groups, all stimuli were the same abstract shapes as in the ABS group. However, across groups, preliminary training involved either the establishment of conditional relations with simultaneous (SMTS) or delayed (DMTS) matching‐to‐sample with 0 s, 3 s, 6 s, or 9 s between the abstract C stimuli and the meaningful pictures. For the ABS and the PIC groups, 16.7% and 83.3% of participants formed classes, respectively. Preliminary training with SMTS and DMTS with 0 s, 3 s, and 6 s produced a linear increase in the likelihood of equivalence class formation, 41.7%, 50%, and 75%, respectively. Increasing the duration of delay further from 6 s to 9 s produced a substantial decline, 50%. This experiment extends knowledge about how including meaningful pictures enhances equivalence class formation.
