Reliability of the M-FLEX™: equipment to measure palmar grasp strength in infants

The palmar grasp behavior investigation is frequent in evaluation routine of infants. The aim of this study was to determine the reliability of an instrument for measuring palmar grasp strength in infants from birth to four months of age. Thirty-nine healthy infants from both sexes from birth to four months of age were evaluated and divided into three groups (“SC”, “FR”, “BL”) according to the city they came from. The equipment under test is called M-FLEX^®, which provides maximum grasp strength (FMAX), mean grasp strength (FMEAN) and grasp time (GRT) values. The repeatability and reproducibility of measures produced by the M-FLEX™ were verified. Three measurements were obtained (M1, M2, M3) from both hands, with the infant's face turned to the right. To calculate the repeatability, the three measures were compared to themselves in each group. For reproducibility, the difference between the averages of M1 of the three variables provided by M-FLEX™ was verified in the three sampling sites. The statistical tests used were ANOVA, Pearson's correlation and calculation of the intra-class correlation coefficient (ICC) with their respective confidence intervals (CI). The M-FLEX™ proved to be an outfit that provides measures capable of characterizing the palmar grasp phenomenon in infants.     

Development and validation of a novel instrument to measure pedestrians’ smartphone use: The Smombie Scale

This study aimed to develop and verify the psychometric properties of the Smombie Scale, a new instrument to measure pedestrians’ smartphone use. The instrument development process comprised two phases: instrument development and psychometric evaluation. Data were collected from September to October 2020 using the “Invite” panel aggregator. The link to the online questionnaire was sent via smartphone text message to 400 young adults aged 18–39 years and yielded 398 valid responses. We randomly selected 200 participants for the exploratory factor analysis; the remaining 198 participants were selected for confirmatory factor analysis. The Smombie Scale comprises 15 items and four factors: (a) perceived risk; (b) stationary smartphone use, always on the smartphone; (c) pending instant message; and (d) smartphone dependency. Model fit was statistically significant (χ²/df = 2.20). The analyses indicated a sufficient goodness-of-fit index of 0.93, a comparative goodness-of-fit index of 0.95, a normed fit index and Tucker–Lewis index of 0.91, and a root mean square error of approximation of 0.07. The scale was also found to have sufficient reliability (Cronbach’s alpha = 0.83). The newly developed Smombie Scale is valid and reliable in measuring pedestrians’ smartphone use among young adults. The Smombie Scale shows evidence of being suitable for evaluating smartphone-distracted pedestrians. Its results can provide data for drafting educational programs to prevent smombie behaviors and deal with potential risks.     

Development and validation of the Intervention Skills Profile–Skills: A brief measure of student social-emotional and academic enabling skills

The purpose of this study was to support the development and initial validation of the Intervention Selection Profile (ISP)–Skills, a brief 14-item teacher rating scale intended to inform the selection and delivery of instructional interventions at Tier 2. Teacher participants (n = 196) rated five students from their classroom across four measures (total student n = 877). These measures included the ISP-Skills and three criterion tools: Social Skills Improvement System (SSIS), Devereux Student Strengths Assessment (DESSA), and Academic Competence Evaluation Scales (ACES). Diagnostic classification modeling (DCM) suggested an expert-created Q-matrix, which specified relations between ISP-Skills items and hypothesized latent attributes, provided good fit to item data. DCM also indicated ISP-Skills items functioned as intended, with the magnitude of item ratings corresponding to the model-implied probability of attribute mastery. DCM was then used to generate skill profiles for each student, which included scores representing the probability of students mastering each of eight skills. Correlational analyses revealed large convergent relations between ISP-Skills probability scores and theoretically-aligned subscales from the criterion measures. Discriminant validity was not supported, as ISP-Skills scores were also highly related to all other criterion subscales. Receiver operating characteristic (ROC) curve analyses informed the selection of cut scores from each ISP-Skills scale. Review of classification accuracy statistics associated with these cut scores (e.g., sensitivity and specificity) suggested they reliably differentiated students with below average, average, and above average skills. Implications for practice and directions for future research are discussed, including those related to the examination of ISP-Skills treatment utility.     

FACES—A database of facial expressions in young, middle-aged, and older women and men: Development and validation

Faces are widely used as stimuli in various research fields. Interest in emotion-related differences and age-associated changes in the processing of faces is growing. With the aim of systematically varying both expression and age of the face, we created FACES, a database comprising N=171 naturalistic faces of young, middle-aged, and older women and men. Each face is represented with two sets of six facial expressions (neutrality, sadness, disgust, fear, anger, and happiness), resulting in 2,052 individual images. A total of N=154 young, middleaged, and older women and men rated the faces in terms of facial expression and perceived age. With its large age range of faces displaying different expressions, FACES is well suited for investigating developmental and other research questions on emotion, motivation, and cognition, as well as their interactions. Information on using FACES for research purposes can be found at http://faces.mpib-berlin.mpg.de.     

Are postural adjustments during reaching related to walking development in typically developing infants and infants at risk of cerebral palsy?

BackgroundIn typical development, postural adjustments during reaching change in the second half of infancy, including increasing rates of direction-specific adjustments. These changes are absent or different in infants at risk of cerebral palsy (CP). To discover whether these changes are related to acquisition of independent walking, we studied postural adjustments during reaching in infants before and after they learned to walk.MethodsTen typically developing (TD) infants and 11 infants at very high risk (VHR) of CP were assessed before and after they learned to walk. Reaching movements were elicited during supported sitting, while surface electromyography was recorded of arm, neck, and trunk muscles. Percentages of direction-specific adjustments (first level of control), and recruitment patterns and anticipatory activation (second level of control) were calculated.ResultsIn both groups, postural adjustments during reaching were similar before and after acquisition of independent walking. Direction-specificity increased with age in typically developing infants but not in VHR-infants.ConclusionIncreasing age rather than the transition to independent walking is associated with increasing direction-specificity of TD-infants during reaching while sitting, while infants at very high risk of CP show no increase in direction-specificity, suggesting that they gradually grow into a postural deficit.     

Development and validation of the Drivers’ Emotional Intelligence Inventory (EMOVIAL)

Road fatalities involving young road users have become a global health issue. Although human factors are known to be involved in road fatalities, little research has examined the way in which emotional competencies may affect road accidents. With the aim of filling this gap we describe the development and validation of a scale for measuring emotional intelligence when driving. The EMOVIAL inventory consists of nine items distributed across three dimensions (attention to emotions while driving, clarity of emotions while driving, and emotional regulation while driving). Analysis of its psychometric properties showed it to be valid and reliable. The paper discusses how the scale may be used to improve road safety.

The Other As Shamer Scale – 2: Development and validation of a short version of a measure of external shame

External shame arises from the perception of negative judgements about the self in the mind of others and is currently measured by Other As Shamer Scale (OAS). This scale has been used in numerous studies. This study sought to develop a valid and reliable shorter form of the scale, called OAS2, in an adult sample of 690 participants, using experts’ item ratings and Confirmatory Factor Analysis. The OAS2 consisted of 8 items, which replicated the unidimensional structure of the OAS (Matos et al., 2011) and revealed a good fit. The OAS2 had good internal consistency (.82), similar to the longer version. The OAS2 has good concurrent and divergent validity, being highly correlated with the OAS (r = .91). The OAS and OAS2 have very similar significant correlations with measures of internal shame, psychopathology and anger, with no significant difference between them. Our results, suggest that the OAS2 is an economic, valid and reliable measure of external shame.     

Transition to Crisis-Free Development: A Myth or Reality?

This article substantiates the thesis that the outlines of the future and present can be made visible and comprehensible by applying a new methodology for cognition of regularities in the human community development. This methodology made it possible to define that there have been and are only two paradigms of the human system development in the entire multicentury course of the human community development. Cycles, crises, chaos, and all negative phenomena are nothing else but natural products of the second, indirect paradigm of development. The new model of life organization at each local level is at the same time the former, first development paradigm, based on the direct interconnection between production and consumption of specific human beings, but raised onto the new high-tech level. Practical realization of this model is the only feasible precondition for the transition to sustainable and crisis-free development.     

Mature Ego Development: A Gateway to Ego Transcendence?

This paper explores whether the highest stage in ego development is indicative of ego-transcendence as I initially surmised. Overall, I will explore some of the similarities and differences between rational awareness of the limits of representational thought and genuine postsymbolic knowing. I will present the research territory with a linear and a non-linear model of human development. Both models can accommodate both Eastern and Western self theories including ego development theory and Alexander's levels of mind. Next, I will outline an alternative developmental trajectory based on Alexander's notion of the shifts in the dominant mode of processing from personal–verbal–discursive to transpersonal–postsymbolic. Then, I will present ego development theory as I conceive of it now and outline the important characteristics of the highest stage (Cook-Greuter, 1999). Finally, I will consider the question of whether and in what way the Unitive ego stage is related to higher consciousness and introduce two testable propositions to clarify the issue.     

Narcissism,psychic recognition,and affective validation: A homage to the “later Rosenfeld”

Abstract

Recalling his own participation in a daily group seminar with Rosenfeld and taking this experience as his starting point, the Author describes and discusses the later Rosenfeld’s approach to working with severely disturbed narcissistic patients. Through a detailed analysis of a supervision of a session with a psychotic patient, this paper essentially highlights how important it is to construct a (cognitive and affective) basic common ground in order to subsequently proceed to interpretations of transference. In particular, the paper brings to light those elements allowing the creation of that basic cognitive-affective ground that is necessary to profitably (in a manner useful to the patient) connect the relational events narrated and acted by the patient with the hic et nunc of analytic interaction.     

Development of mother–infant interaction in tickling play: The relationship between infants’ ticklishness and social behaviors

This study examined the development of mother–infant tickling interaction and the relationship between infants’ ticklishness and social behaviors including infants’ looking at mothers’ face, mothers’ narrative tickling, and mothers’ laughter. Twenty-two Japanese infants aged 5 months (n = 10, five girls) and 7 months (n = 12, four girls) and their mothers were videotaped. Results revealed that the mothers’ narrative tickling was more frequent at 7 than at 5 months and the infants’ strong ticklishness showed the same tendency. The infants’ strong ticklishness was linked with the occurrence of other social behaviors. In conclusion, infants’ ticklishness was heavily connected with social behaviors. The mode of the tickling interaction at 7 months was different from that at 5 months especially in the increase of mother’s narrative tickling. A possible function of such mother’s narrative tickling to facilitate infant active communication at a higher cognitive level including anticipation, was discussed.
