The Professional Counselor /Volume 5, Issue 2 275 Subtypes Those with hyposensitivities, one subtype of SPD, often have a high threshold for sensation, are under- sensitive, and receive or process too few stimuli (Dunn, 1997, 2001; James et al., 2011; Katz, 2006; Walbam, 2013; Withrow, 2007). A child with hyposensitivities may seem to have poor social skills and miss social cues; some behavioral examples include not hearing a teacher calling his or her name, being unaware of food on the face, or lacking culturally appropriate personal space. Social skill deficits can negatively impact children’s friendships and group participation in both academic and social environments (Dunn, 1997; Kranowitz, 2005; Withrow, 2007). Children with hypersensitivities, a second subtype of SPD, have a low threshold for sensation and may receive an overwhelming amount of stimuli, be unable to prioritize their sensory messages and be easily overstimulated (Dunn, 1997, 2001; James et al., 2011; Katz, 2006; Walbam, 2013; Withrow, 2007). As a coping technique against stimuli perceived as uncomfortable and even painful, children with hypersensitivies may have heightened alertness, act aggressively toward others in response to perceived threats, and engage in behavioral outbursts and rigid routines in attempts to avoid or escape stimuli (Dunn, 1997; Withrow, 2007). These children may be described as generally anxious, aggressive, distracted or unfocused, or as picky eaters. Lastly, some children with a third subtype of SPD crave and actively seek sensory input and increased stimuli (Dunn, 1997, 2001). These children may seek constant movement to receive sensations from their environment, and exhibit behaviors including running, jumping, chewing, tapping, humming and squeezing (Dunn, 1997, 2001). Individuals with sensory-seeking behaviors may appear impulsive, unpredictable, and have inappropriate personal space which may negatively impact academics and social relationships. Children who seek sensations may be described as rambunctious, aggressive, or bouncing off the walls (sometimes literally). They may seek spicy foods and not be bothered by intense flavors. Sensitivities and sensation seeking occur on a spectrum from mild to severe (James et al., 2011). Furthermore, these variations can present differently in each of the seven senses (Dunn, 1997, 2001), and children can even experience both hypersensitivities and hyposensitivities within the same sense (Withrow, 2007). This circumstance may baffle parents, who question how a child can watch a movie at a loud volume at home, yet be unable to tolerate the noise of a crowded restaurant. Children and the adults around them may need assistance recognizing children’s placement on the hyposensitivity, hypersensitivity and sensory-seeking spectrums before, during and after an event which can facilitate children successfully coping and thriving in various settings. Prevalence Researchers have estimated that SPD occurs in approximately 5–17% of children (Ahn et al., 2004; Ben- Sasson et al., 2009). In one study examining the prevalence of SPD in children 4–6 years old, the parents of incoming kindergarten students in one U.S. school district ( N = 1,796) were asked to complete the Short Sensory Profile, a parental-report screening tool used to determine parents’ perceptions of SPD correlates (Ahn et al., 2004). Approximately 14% of those who completed the survey (with a 39% return rate) met the criteria for SPD. However, researchers conservatively estimated that if all non-responders were free from meeting the SPD criteria, then approximately 5% of this population would meet the screening criteria for SPD. Thus, the number of incoming kindergarten students who met the criteria for SPD based on parental perceptions ranged from 5–14%. Similarly, Ben-Sasson et al. (2009) used a longitudinal birth cohort sample of children to study sensory over-responsivity (SOR) and related correlates. They found that nearly 17% of the 7–11 year olds in their study ( N = 925) had clinically significant elevated SOR scores. However, these researchers believe the number to be a conservative estimate of the population, as children with diagnosed medical and developmental conditions were excluded from the study.
