Introduction The present paper introduces a new scale that aims to assess emotional reactivity. We conclude that PERS might prove to be a useful tool to assess emotional reactivity more precisely.ġ. Moreover, PERS includes three non-scorable items to measure subjective report of physiological changes. It contains 5 positive valence items and 5 negative valence items in each dimension. ![]() PERS is guided by the tripartite model of emotional reactivity (activation, intensity and duration) and it also includes valence (positive and negative emotions). We therefore introduced a new scale–the Perth Emotional Reactivity Scale (PERS)–which overcomes the identified problems. Moreover, ERS, which does not suffer from this problem, does not include valence and it was mainly validated with adolescents. ![]() Our review concluded that most of the scales are either too broad (BIS/BAS, EATQ), or too narrow (EIS, AIM). We discussed the Behavioral Inhibition/Behavioral Activation (BIS/BAS) scale, the Early Adolescence Temperament Questionnaire (EATQ), the Affect Intensity Measure (AIM), the Emotion Intensity Scale (EIS), and the Emotional Reactivity Scale (ERS). PMID 4708117.The goal of this article is to provide a review of the literature on conceptual aspects and measurement of emotional reactivity, and to propose a new measurement of emotional reactivity that addresses the problems identified in the review.

Unobtrusive research refers to methods in which the researchers are able to obtain information without interfering in the research itself. Ī common solution to reactivity is unobtrusive research that can replace or augment reactive research. These authors investigate the consequences, both intended and unintended, of such public measures. ![]() Įspeland & Sauder (2007) took a reactivity lens to investigate how rankings of educational institutions change expectations and permeate institutions. In addition there may be important individual differences in how participants react to a particular self-report measure. For example, both confidence ratings and judgments of learning, which are often provided repeatedly throughout cognitive assessments of learning and reasoning, have been found to be reactive. Reactivity can also occur in response to self-report measures if the measure is elicited from research participants during a task. ![]() The Pygmalion effect occurs when students alter their behavior to meet teacher expectations. Īn experimenter effect occurs when the experimenters subtly communicate their expectations to the participants, who alter their behavior to conform to these expectations. Reactivity is not limited to changes in behaviour in relation to being merely observed it can also refer to situations where individuals alter their behavior to conform to the expectations of the observer. The John Henry effect, a specific form of Hawthorne effect, occurs when the participants in the control group alter their behavior out of awareness that they are in the control group. The Hawthorne effect occurs when research study participants know they are being studied and alter their performance because of the attention they receive from the experimenters. It is a significant threat to a research study's external validity and is typically controlled for using blind experiment designs. The change may be positive or negative, and depends on the situation. Reactivity is a phenomenon that occurs when individuals alter their performance or behavior due to the awareness that they are being observed.
